Question

What is the value of v?

Answer 1

Answer:

The value of v is 9.5.

Step-by-step explanation:

Given : Equation $\frac{4}{5}(v-7)=2$

To find : What is the value of v?

Solution :

Step 1 - Write the equation,

$\frac{4}{5}(v-7)=2$

Step 2 - Multiply 5/4 both side,

$\frac{4}{5}(v-7)\times \frac{5}{4}=2\times \frac{5}{4}$

$v-7=\frac{5}{2}$

Step 3 - Add 7 both side,

$v-7+7=\frac{5}{2}+7$

$v=\frac{5+14}{2}$

$v=\frac{19}{2}$

$v=9.5$

Therefore, The value of v is 9.5.

Answer 2

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
