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
The correct equation is:
2a = 13
The equation that represents Justin's age, a, is:
a + 12 = 13
To find Justin's age, we need to set up an equation representing the relationship between Kendra's age and Justin's age.
We know that Kendra's age is half the age of Justin. And we also know that Kendra is 13 years old.
So, we can write the equation as follows:
Kendra's age = Justin's age / 2
Substituting the given values:
13 = Justin's age / 2
To find Justin's age, we need to solve for 'a' in the equation. We can do this by multiplying both sides of the equation by 2:
2 * 13 = Justin's age
Simplifying the equation:
26 = Justin's age
So, the equation representing Justin's age is:
a = 26
