13a = 2
13 a equals 2

2a = 13
2 a equals 13

12a = 13
Start Fraction 1 over 2 End Fraction a equals 13

a + 12 = 13

Answer 1

To find the equation that represents Justin's age, we need to understand the information given.

We know that Kendra's age is half the age of Justin and that Kendra is 13 years old.

This means that Justin's age must be twice Kendra's age. So, if Kendra is 13, Justin's age can be calculated by multiplying her age (13) by 2.

Therefore, the correct equation representing Justin's age is: 2a = 13

Here, 'a' represents Justin's age, and multiplying Kendra's age (13) by 2 on the left side of the equation gives us the equation 2a = 13.

Answer 2

To represent Justin's age, we can use the equation:

a = 2k

where "a" represents Justin's age and "k" represents Kendra's age.

Given that Kendra is 13 years old, we can substitute k = 13 into the equation:

a = 2 * 13

Simplifying, we get:

a = 26

Therefore, the correct equation representing Justin's age, a, is "a = 26."
