The correct equation representing Justin's age is:
a + 12 = 13
The correct equation that represents Justin's age, a, is "2a = 13".
To find Justin's age, we need to use the information given: Kendra's age is half the age of Justin, and Kendra is 13 years old.
If Kendra is 13 years old and her age is half of Justin's age, we can set up the equation:
Justin's age = 2 * Kendra's age
Substituting in the value we know, we get:
Justin's age = 2 * 13
Simplifying, we find:
Justin's age = 26
Therefore, the equation that represents Justin's age is:
2a = 26
