The correct equation that represents Justin's age, a, is 2a = 13.
The correct equation representing Justin's age, a, is:
2a = 13
To find Justin's age, we need to understand that Kendra's age is half the age of Justin's. We are given that Kendra is 13 years old.
Let's represent Justin's age as 'a'. Since Kendra's age is half of Justin's age, we can write the equation as:
a/2 = 13
Now, to find Justin's age, we need to solve for 'a'. To do that, we can multiply both sides of the equation by 2 to get rid of the fraction:
2(a/2) = 2(13)
This simplifies to:
a = 26
Therefore, Justin's age is 26 years old.
So, the correct equation representing Justin's age is:
2a = 13.
