Kendra's age is half the age of Justin. Kendra is 13 years old. Which of the following equations represents Justin's age, a?
2a = 13
a + 1/2 = 13
1/2a = 13
13a = 2
Let a represent Justin's age. According to the information given, Kendra's age is half the age of Justin. Since Kendra is 13 years old, Justin's age would be double that, or 26 years old.
The equation that represents Justin's age, a, is 2a = 26.
The correct equation that represents Justin's age, a, is '2a = 13'.

The correct equation that represents Justin's age, a, is '2a = 13'.
To find the equation that represents Justin's age, we need to use the information given in the problem statement.
According to the problem, Kendra's age is half the age of Justin. And we also know that Kendra is 13 years old.
Let's denote Justin's age as "a".
Since Kendra's age is half of Justin's age, we can write the equation as:
Kendra's age = Justin's age / 2
Substituting Kendra's age with 13 and Justin's age with "a", we get:
13 = a/2
Now, we need to isolate "a" to one side of the equation.
To do this, we can multiply both sides of the equation by 2:
2 * 13 = 2 * (a/2)
26 = a
So, the equation that represents Justin's age is:
a = 26
Therefore, none of the given options (2a = 13, a + 1/2 = 13, 1/2a = 13, 13a = 2) represents Justin's age correctly.
