Question

If a/b = 7/2, then 2a = ___

A) 4b.
B) 7b.
C) 14b.
D) 2b.

Answer 1

B) 7b

Explanation:

1. Write the equation to solve

`(a)/(b)=(7)/(2)`

2. Solve for a:

`a=(7b)/(2)`

3. Multiply both sides by 2 to obtain the value of 2a:

`2a=2*((7b)/(2))`

4. Solve the equation:

`2a=(14b)/(2)`

`2a=7b`

Answer 2

If a/b = 7/2, then 2a = 7b
