Answer:

1. 2x=5

Divide both by 2, x=2.5

2. y+1.8=14.7

Subtract 1.8 from both sides to isolate the variable, x=12.9

3. 6=1/2z

Multiply each side by 2 to isolate the variable, 12=z

4. 3 1/4 = 1/2+w

Isolate the variable by subtracting 1/2 to both sides, 2 3/4 = w

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.

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.

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:

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.

Answer:

WY = 180

Step-by-step explanation:

the diagonals of an isosceles trapezoid are congruent , so

ZX = WY , that is

8y - 4 = 7y + 19 ( subtract 7y from both sides )

y - 4 = 19 ( add 4 to both sides )

y = 23

Then

WY = 7y + 19 = 7(23) + 19 = 161 + 19 = 180

Answer:

Isolate the mDivide both sides by 8:Simplify the fraction:Find the greatest common factor of the numerator and denominator:Factor out and cancel the greatest common factor:

Then you get m=1/2

Step-by-step explanation:

The value of the 24th term is 16.

where

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

Answer:

5.12$

Step-by-step explanation:

I know this because when your dealing with 20% think of it like 1/5.

Know 1/5 of 25.60 is 5.12 how I can calculate this is by timesing 5.12 by 5.

Here is what is would look like.

5.12 x 1=5.12$

5.12 x 2=10.24$

5.12 x 3=15.36$

5.12 x 4=20.48$

5.12 x 5=25.60$

And there's your answer(the last one by the way:))

If you want another example based upon 1/5 and 20% then say they were

30 cows and 30 horses 1/5 of them or 20% of them are sitting how many are sitting.

And since it is 1/5 what times 5 would=60 ?

It would be 12 so 20% of 60 is 12, do you understand what I am saying.

Hope this helps have a great day:)

Answer:

What are we supposed to find

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%.

Answer:

1. 360 miles

2. 1.5m/m

3. 4 hours

Step-by-step explanation:

1. d (distance) = v (speed) x t (time)

d = 120 x 3

d = 360

2. v = d/t

v = 6/4

v = 1.5

3. t = d/v

t = 200/50

t = 4

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

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:

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.

Answer:

x>1

Step-by-step explanation:

In order to do this, we can take the inequality:

3+2x>5

now there are constants on both sides meaning we can combine them like the following:

3+2x>5

-3      -3

------------

2x>2

Now we can simplify

2x/2>2/2

therefore, the answer is x>1

In order to graph this on a line you would need to put in a circle which is not filled in because x isn't equal to and greater than 1 so we put in a blank circle and since x is always going to be greater than 1, we would put a line that keeps going on.

You would put this line to the right of 1

Angel is 3 years younger than seven times Nancyś age and if Angel is 25 then Nancy is 4 years old.

Two or more expressions with an Equal sign is called as Equation.

Given that Angel is 3 years younger than seven times Nancyś age.

Let N be Nancy's age.

We know that Angel's age is 7N - 3.

We also know that Angel is 25.

So we can set up the equation: 7N - 3 = 25.

7N-3=25

Add 3 on both sides to isolate N

7N=28

Divide both sides by 7

N=4

Hence, if  Angel is 25 then Nancy is 4 years old.
