Question

5v + 7f =28.70 if f is 2.85

Answer 1

Hey!

First, let's write the problem.

`5v+7\left(2.85\right)=28.7`
Multiply
`7` with
`2.85`.

`5v+19.95=28.7`
Subtract
`19.95` from both sides.

`5v+19.95-19.95=28.7-19.95`

`5v=8.75`
Divide both sides by
`5`.

`(5v)/(5)=(8.75)/(5)`

`v=1.75`

Let me know if you have any questions regarding this problem!
