Question

What is the value of v?

4/5(v−7)=2



Enter your answer in the box.
v =

Answer 1

Basically, this is saying that 80% of (x) = 2 so you have know what the whole would be. It would be 2.5 because 80% of 2.5 is 2. So because you are subtracting 7 from v to get 2.5, you have to add 2.5 to 7 to get v. V=9.5

Answer 2

The value of v is 9.5.

Explanation:

Given : Equation
`(4)/(5)(v-7)=2`

To find : What is the value of v?

Solution :

Step 1 - Write the equation,

`(4)/(5)(v-7)=2`

Step 2 - Multiply 5/4 both side,

`(4)/(5)(v-7)* (5)/(4)=2* (5)/(4)`

`v-7=(5)/(2)`

Step 3 - Add 7 both side,

`v-7+7=(5)/(2)+7`

`v=(5+14)/(2)`

`v=(19)/(2)`

`v=9.5`

Therefore, The value of v is 9.5.
