a + 12 = 13
a plus Start Fraction 1 over 2 End Fraction equals 13
13a = 2
13 a equals 2
2a = 13
2 a equals 13
1/2a = 13
The correct equation is: 2a = 13
The equation that represents Justin's age, a, is "a + 26 = 13"
To solve this question, you can use the information given that Kendra's age is half the age of Justin. We also know that Kendra is 13 years old.
Let a represent Justin's age.
According to the given information, Kendra's age (13) is half the age of Justin, so we can write the equation as:
a/2 = 13
Hence, the correct representation of Justin's age is "a/2 = 13".
