Kendra’s age is half the age of Justin. Kendra is 13 years old. Which of the following equations represents Justin’s age, a ?(1 point)
Responses
13a = 2
13 a equals 2
2a = 13
2 a equals 13
1/2a = 13
Start Fraction 1 over 2 End Fraction a equals 13
a + 1/2 = 13
The correct equation is 2a = 13.
The correct equation representing Justin's age is "2a = 13".
To find Justin's age, we can use the information provided in the question. We know that Kendra's age is half the age of Justin and that Kendra is 13 years old.
So, we can set up an equation to represent this relationship. Let's assign the variable "a" to Justin's age.
The equation that represents Kendra's age being half of Justin's age is:
Kendra's Age = 1/2 * Justin's Age
Since we know that Kendra's age is 13, we can plug in this value into the equation:
13 = 1/2 * a
Simplifying this equation, we get:
2 * 13 = a
26 = a
Therefore, Justin's age, a, is 26.
The correct equation representing Justin's age is:
2a = 13
