Question

Answer 1

A. 4 (on edgenuity)

Explanation:

Answer 2

4

Explanation:

Given,

r = 10

Let's create an equation,

`3r = 10 + 5s`

plugging the value of r

`3 * 10 = 10 + 5s`

Multiply the numbers

`30 = 10 + 5s`

Move 5s to L.H.S and change its sign

Similarly, Move 30 to R.H.S and change its sign.

`- 5s = 10 - 30`

Calculate

`- 5s = - 20`

The difference sign ( - ) should be cancelled on both sides

`5s = 20`

Divide both sides of the equation by 5

`(5s)/(2) = (20)/(5)`

Calculate

`s = 4`

The value of s is 4.

Hope this helps..
