Answer 1

Answer:

40

Step-by-step explanation:

70% of something is 28.

We'll use the variable x to hold our value. 70% can be written as 0.7. Rewriting our equation, we get:

0.7 * x = 28.

Lets divide 0.7 over. Our new equation is:

x = 28 / 0.7.

You get that x = 40.

70% of 40 = 28.

2a+10b-8-2(4a-6) and -6a+10b+c

Answers

Answer:

see below

Step-by-step explanation:

We are given 2 equations:

[tex]2a+10b-8-2(4a-6)\\-6a+10b+c[/tex]

We are told to find c to make them equivalent, so we can make them equal to each other:

2a+10b-8-2(4a-6)=-6a+10b+c

To find c, we have to isolate it, here are the steps:

2a+10b-8-2(4a-6)=-6a+10b+c

subtract 10b from both sides

2a-8-2(4a-6)=-6a+c

rearrange left side

2a-2(4a-6)-8=-6a+c

distribute the positive 2 to the terms in parenthesis

2a-(8a-12)-8=-6a+c

distribute -1 to the terms in parenthesis

2a-8a+12-8=-6a+c

simplify

-6a+4=-6a+c

add -6a to both sides

4=c

Hope this helps! :)

Answer:

1. slope = 12

  y-intercept = 1/3

2.slope = 1/4

  y-intercept= -12

3.slope = 3

  y-intercept = 2

Step-by-step explanation:

When you get an equation for a graph, the co-efficient infront of the x (The number by the x) is the slope.

The equation for the y-intercept:

When solving for y-intercept, you replace y in the equation with 0 and make x the subject.

Example:
y = 12x - 4

0=12x - 4

-12x = -4

divide both sides by negative 12 since we want only positive x

[tex]\frac{-12x}{-12} =\frac{-4}{-12}[/tex]

x = [tex]\frac{1}{3}[/tex]

Therefore, the y-intercept = 1/3

Answer:20.7 units²

Step-by-step explanation: volume of a rectangular prism is L×W×H

therefore 82.8=L×W×the height which is 4 units so if u do 4×L×W you get 4LW which is the volume

(4LW=82.8) now divide 82.8 by 4LW to get the value of LW. The value of LW is an area of one of the bases because area is L×W which is basically LW
