Question

A 2a = 13
B a+ ½=13
C 13a=2
D 1/2a=13

Answer 1

The answer is A) 2a = 13.

Given that Sam's age (S) is half the age of Justin (J), we can write the equation: S = J/2.

Given that Sam's age (S) is 13 years old, we can substitute this value into the equation: 13 = J/2.

To solve for Justin's age (J), we multiply both sides of the equation by 2: 2(13) = J.

Simplifying the equation, we get: 26 = J.

Therefore, Justin's age is 26 years old.
