Answer:
Step-by-step explanation:
The direct proportion equation is y = kx which reads, "y is directly proportional to x". k is the constant of proportionality. In our case, we read this is as, "the number of calories is directly proportional to the number of apples eaten." Our equation would look like c = ka. We first are given that a = 4 and = 380. We will use that to solve for k:
380 = k4 so
k = 95. Now that know the value of k, we will use that along with the number of calories (1045) to find the number of apples, a:
1045 = 95a so
a = 11
This means that it will be 11 apples that contain 1045 calories.
3(x - 1) - 8 = 4(1+x) + 5
Answer:
x= 20
Step-by-step explanation:
Step 1- Distribute into the parenthesis.
3x-1(3)-8= 1(4)+4x+5
Step 2- Multiply
3x-3-8= 4+4x+5
Step 3- Add.
3x-3-8= 4x+9
Step 4- Subtract 3x to both sides to move the variable to one side.
3x-11= 4x+9
-3x -3x
Step 5- Subtract 9 to both sides.
-11= 1x+9
-9 -9
-20= x
Exchange the signs.
20= x
Answer:
x = -20
Step-by-step explanation:
3(x - 1) - 8 = 4(1+x) + 5
3x - 3 -8 = 4 + 4x + 5
3x - 11 = 9 + 4x
-x = 20
x = -20

I REALLLYYY NEED HELP WITH THIS ONE I DONT UNDERSTAND AT ALL AND MY TEACHERS ARE NOT HELPING ME...please?? Point B is between A and C. The distance between A and B is 1/2 of AC. What is the coordinate of B? B is located at on the number line.
To find the midpoint, we must take the sum of both values and then divide by two.
In this case, our values are -6 and 14
-6 + 14 = 8
8 / 2 = 4
B is located at 4 on the number line.

Which expression could be used to represent a 45% increase? (Question 9)
Answer:
Options (A) and (B)
Step-by-step explanation:
Question (9)
Let a number = x
45% increase in the given number will be = x + (45% of x)
= x + [tex]\frac{45x}{100}[/tex]
= x + 0.45x
= x(1 + 0.45)
= 1.45x
Therefore, there will be the two expressions,
A). 1.45x
B). x + 0.45x
Options (A) and (B) will be the correct options.

Step-by-step explanation:
Its much closer to a whole number than it is to a fraction.
Did I do this right?
Answer:
no i dont think so
Step-by-step explanation:
1) multiply both sides by p
5/9=-10p
2) divide by -10 to get p
5/9 divided by -10/1
(keep, change flip)
5/9* -1/10
-5/90
therefore p=-5/90
Answer:
No, the answer is -18
Step-by-step explanation:
[tex]\frac{5}{9}[/tex]p = -10
[tex]\frac{5p}{9}[/tex] = -10 CROSS MULTIPLY
-90=5p DIVIDE BOTH SIDES BY 5
-18 = p

HELP!!!
Answer:
No Solution
Step-by-step explanation:
I have tried it a few times and there seems to be no solution. x can't be solved for.
Answer:
no solution
Step-by-step explanation:
Given
3(2x - 1) + 5 = 6(x + 1) ← distribute parenthesis on both sides
6x - 3 + 5 = 6x + 6 , that is
6x + 2 = 6x + 6 ( subtract 2 from both sides )
6x = 6x + 4 ( subtract 6x from both sides )
0 = 4 ← not possible
This indicates the equation has no solution
pls help this is due in 30 min
Thank you sm

What is the relationship between Za and Zb?
Answer: B
Step-by-step explanation:
∠a and ∠b are complementary angles. Complementary angles are two angles adjacent to each other that add up to 90°. We know this is true because of the 90° angle that is labelled.
Vertical angles are not adjacent to each other. They are across from each other, connected by the angle. They are equal in angles. It is clear that ∠a and ∠b are not equal in angles. Therefore, they are complementary angles.

Which has a larger value: 4 x 10^2 or 7 x 10^4?
Answer:
7 x 10^4
Step-by-step explanation:
4 x 10^2 equals to 400, when 7 x 10^4 equals to 70,000
Answer:
[tex]7[/tex]× [tex]10^{4}[/tex]
Step-by-step explanation:
Because the exponent means that the number is being multiplied by itself that many times. Like [tex]10^{4}[/tex] means 10000 and that times 7 is 70000.
[tex]10^{2}[/tex] would be 100 and 100 times 4 is 400. Now to determine is 400 or 70000 larger? 70000 is larger.
Hope that helps and have a great day!
