What is the value of the 24th term is the fourth term is 6 and the eighth term is 8
A. 24
B. 16
C. 8
D. 4.5
The value of the 24th term is 16.
Arithmetic progression:aₙ = a + (n - 1)dwhere
a = first term
d = common difference
n = number of terms
Therefore,
6 = a + 3d
8 = a + 7d
let's find a and d
2 = 4d
d = 2 / 4
d = 1 / 2
6 = a + 3 / 2
a = 6 - 3 /2
a = 4.5
Therefore, the 24th term can be found as follows;
24th term = 4.5 + 23(0.5)
24th term = 4.5 + 11.5
24th term = 16

Part A:
Rewrite without absolute value for the given conditions:
1) y = |x−3|+|x+2|−|x−5|, if x > 5
2) y = |10-x|, if x<10
Part B:
Write the absolute value equations in the form x−b=c (where b is a number and c can be either number or an expression) that have the following solution sets:
1) All numbers such that x≤5.
2) All numbers such that x≤−14.
Again, thank you so much if you do all of these!
Answer:
Step-by-step explanation:
Rewrite without absolute value for the given conditions:
1) y = |x−3|+|x+2|−|x−5|, if x > 5
y = x-3 + x + 2 - (x-5)
y = x + 4
2) y = |10-x|, if x<10
y = 10 - x
In both cases, the value of x is held to values that make the absolute value notation redundant, so they can be removed.
===============
Write the absolute value equations in the form x−b=c (where b is a number and c can be either number or an expression) that have the following solution sets:
I actually don't understand the question. Rewrite the above equations, or make new ones? Sorry.1) All numbers such that x≤5
x≤5 kinda does it for me. X can be any number less than or equal to 5. Ta da. (?)
2) All numbers such that x≤−14.
x ≤ -14

Write the equation of the line that
passes through the point (4, 3) and is
PERPENDICULAR to the line y = 2x - 4
Answer:
y=-1/2x+2
Step-by-step explanation:
First, the slope of perpendicular line have negative reciprocal coefficients. In this case the coefficient is 2, The reciprocal of 2 is 1/2 and the negative of 1/2 is -1/2. So x will have a coefficient of -1/2.
Second, find the equation with a slope of -1/2 that passes through (-2,3). There are a few ways to do this. I like to plug the given x value into the expression -1/2x, so -1/2(-2) which equals positive 1 and for the line to pass through the point (-2,3) you need to add 2. So: y=-1/2x+2
Westside high’s 2015 senior-class science enrollment is summarized by the venn diagram. chemistry, biology, and physics class enrollments are denoted by the sets c, b, an p, respectively. how many students are in the 2015 senior class? how many students are taking chemistry and biology, but not physics? how many students are not taking science?
There are 63 students are in the 2015 senior class, 5 students who are taking chemistry and biology, but not physics, and 18 students who are not taking science.
What is the Venn diagram?A Venn diagram is a graphic that employs circles to depict connections between objects or finite groups of objects.
Circles that overlap share characteristics, but circles that do not overlap do not.
In the Venn diagram the following data is observed;
Chemistry - 9
Biology - 11
Physics - 7
Biology+Chemistry- 5
Biology+Physics - 4
Physics+Chemistry -6
Physics+Chemistry+Biology-3
None of the three - 18
Total -- 63
We can clearly see from the table that the grand total of the table of data is the total number of pupils in the senior class. In other words, the total number of people is 63.
In addition, there are 7 students who are taking chemistry and biology but not physics.
The number of students who do not take science is equal to the number of students who do not take biology, chemistry, or physics, i.e. the 18 students outside the circle.
There are 63 students are in the 2015 senior class
There are 5 students who are taking chemistry and biology, but not physics.
There are 18 students who are not taking science.
Hence there are 63 students are in the 2015 senior class, 5 students who are taking chemistry and biology, but not physics, and 18 students who are not taking science.

hi can you help me with this problem ? 15 points
Answer:
30 cakes
Step-by-step explanation:
For one cake alone, find a common denominator (which is 6). So [tex]2\frac{2}{3}[/tex] ([tex]\frac{8}{3}[/tex]) is equal to [tex]\frac{16}{6}[/tex] cups. [tex]\frac{1}{2}[/tex] is [tex]\frac{3}{6}[/tex] cups.
So for one cake, it takes [tex]\frac{19}{6}[/tex] cups of flour. Henry has [tex]\frac{570}{6} = 95[/tex] cups of flour.
If you divide the 570 by 19, Henry can make 30 cakes.

What is the solution to the equation?
x^2=40
Will give brainliest if correct and explained!!
Answer: 2√10
Step-by-step explanation:
A way we can find what x equals, is to find the opposite of what ever sign is on a side, in the equation x^2=40, the opposite of squaring is to find the square root of it.
It is important that what you do to one side, you do to the other.
So we have to square root both sides so we can get rid of the ^2 on x to get x =. This would look like √x^2 = √40
The square root of x^2 would revert back to just x
To find the square root of 40, its important to first see if its a perfect square. In this scenario, it isnt. Because it isnt, we have to find the closest perfect square that we can multiply to get 40, in this equation, the closest would be 4 so we do 4*10.
Then we reduce the 4 by square root and we get 2
Then we cant do anything else with the 10, so we would right the answer as a radical, with the square root you got from the perfect square on the outside and the remainder on the inside of the square root, like x√r where x is the number obtained from square root and r is the remainder that we cant do anything else with.
After doing this, we get the answer 2√10, which can be said "two radical ten"
Rahul was given a large box of 60 chocolates for his birthday. If he eats exactly 4
chocolates each day, how many chocolates would Rahul have remaining 9 days after
his birthday?
Answer:
He'll have 24 chocolates remaining.
Step-by-step explanation:
Lets make an equation to represent the problem where x = the number of days and c = chocolates remaining.
60 - 4x = c
Since he ate four chocolates everyday for 9 days, the x in this equation would be 9.
Multiply 9 by 4 to get 36, Then subtract that from 60 to get 24.
In right triangle ABC, angle C = 90˚. Median AM has a length of 19, and median BN has a length of 18. What is the length of the hypotenuse of the triangle?
Answer:
2[tex]\sqrt{137}[/tex]
Step-by-step explanation:
Solving for the equations,
x² + 4y² = 361
4x² + y² = 324
Add both equations
5x² + 5y² = 685
Divide both sides by 5
x² + y² = 137
Multiply both sides by 4
4x² + 4y² = 548
Now take the square of both sides.
[tex]\sqrt{4x^{2} +4y^{2} } =\sqrt{548}[/tex]
= 2[tex]\sqrt{137}[/tex]
Answer: [tex]2\sqrt{137}[/tex]

Find the equation of a line that passes through the points (3,2) and (5,6).
Leave your answer in the form y=mx+c
Answer:
Step-by-step explanation:This particular answer works out to be undefined because it is a straight line and there is no slope and no equation for it. I will show you how to work it out though so you will know how to do it with other problems. We will still be using the y = mx + b formula. First step is to find m. In order to find the slope we would use the equation:
m = (y2 - y1) / (x2 - x1) Note: The number behind the letter designates which x or y value you will use of the 2 (x, y) plots
m = (-5 - 2) / (3 - 3)
m = -7 / 0 Note: A number divided by 0 is undefined which means your slope is undefined
Since your slope is undefined your equation would be x = 3 because your x values are both 3.
Now let's assume your second (x, y) plot was actually (-3, -5).
m = (-5 - 2) / (-3 - 3)
m = -7 / - 6 Note: A negative divided by a negative is a positive. The negatives cancel each other out.
m = 7/6
Okay now back to our slope-intercept formula.
y = 7/6x + b
Now in order to figure out what b is, we will again take the plot point and plug the values into the equation. You can use either point because either way the answer will come out the same. In this case we will use (3, 2).
2 = 7/6(3) + b
2 = 21/6 + b Note: The easiest way to do the next part is to make the 2 into a fraction over 6
12/6 - 21/6 = b
-9/6 = b or -3/2
So now all we have to do is plug this value into our equation.
y = 7/6x - 3/2

Josue is saving up to buy a new phone. He already has $100 and can save an additional $5 per week using money from his after school job. How much total money would Josue have after 4 weeks of saving? Also, write an expression that represents the amount of money Josue would have saved in ww weeks.
Answer:
$120, 5w+100
Step-by-step explanation:
Josue starts with $100 and earns $5 a week over 4 weeks. That means you multiply 5 by 4 to get $20 dollars earned over 4 weeks. Then you add that to how much money he already has 100+20=$120 after 4 weeks. To get an expression, we have to take the amount of weeks and multiply it by 5 to show the 5 dollars he earns every week (5w) and then add the 100 dollars he already has to it, which gives us 5w+100.

Answer:
3.
a) There are 1, 2, 3, 4, 5, 6 outcomes.
b) There are 3 odd numbers on this die, and they are: 1, 3, and 5
c) There are 3 even numbers on this die, and they are: 2, 4, and 6
4.
a) There are 3 possible outcomes, green, blue, and red
b) There is a 1/3 chance of getting a red, because there is one red out of three possible outcomes.
c) P(R ∪/or G) = P(R) + P(G) - P(R ∩/and G)
replace those with actual values;
P(R or/∪ G) = 1/3 + 1/3 - (1/3 x 1/3) = 2/9
d) There are 2 other colors besides red out of 3, so therefore it is a 2/3 chance
e) The probability of getting a yellow is not mentioned therefore it is impossible.
5.
a) There are 7 possible outcomes
b) There is only one 6 in the spinner out of 7 numbers, so it will be a 1/7 chance
c) There is no 8 mentioned in this spinner, hence this event is impossible.
d) P(2 ∪/or 4) = P(2) + P(4) - P(2 ∩/and 4)
replace them with actual values;
1/7 + 1/7 - (1/7 x 1/7) = 13/49
e) There are 3 even numbers in the spinner, so it is a 3/7 chance
f) There are 4 odd numbers in the spinner, so it is a 4/7 chance
g) There are 8 marbles in a bag, what is the probability of getting a marble? The event has to be certain if you're getting a probability of 1.
6.
a) There are 5 possible outcomes.
b) There is one "T" in the word 'maths', so it would be a 1/5 chance of getting a t since there are 5 letters in total. Though, they want it in decimals so 1/5 = 0.2
c) There are 4 consonants in the word 'maths', so it would be a 4/5 chance of getting a consonant. Though, they want it in decimals so: 4/5 = 0.8
d) There are 3 letters in both 'tame' and 'maths', so 3 letters out of 5 letters (3/5) could be a letter used in 'tame' from 'maths'. Though, they want a percentage so: 3/5 = x/100, solving for x would equal 60%.
