Question

3v/7=6, then v=

a) 1-2/3

b) 2-4/7

c) 14

d) 42

Answer 1

c) 14

Explanation:

The given equation is
`(3v)/(7)=6`.

We need to solve this equation for v, so we multiply both sides of the equation by the multiplicative inverse of
`(3)/(7)` which is
`(7)/(3)` to obtain;

`(7)/(3) * (3v)/(7)=6* (7)/(3)`.

We simplify to obtain;

`v=2* 7`

`v=14`

The correct choice is C.

Answer 2

Answer: option c

Explanation:

To solve this problem you must apply the following proccedure:

- Multiply both sides of the equation by 7.

- Divide both sides of the equation by 3.

Therefore, keeping the steps above on mind, you obtain the result shown below:

`(3v)/(7)=6\\\\(7)(3v)/(7)=6(7)\\\\3v=42\\\\(3v)/(3)=(42)/(3)\\ v=14`
