Kendra's age is half the age of Justin. Kendra is 13 years old. Which of the following equations represents Justin's age, a?
A. 13A=2
B. 1/2A=13
C.2A=13
D.A+1/2=13
The correct equation that represents Justin's age, a, is C. 2A=13.
The correct equation that represents Justin's age, a, is:
C. 2A = 13
According to the information given, Kendra's age is half the age of Justin. Since Kendra is 13 years old, Justin's age (a) would be twice that:
2A = 13
To solve this problem, we can set up the equation based on the given information.
Let's assume Justin's age is represented by the variable "A."
According to the problem, Kendra's age is half the age of Justin. It is given that Kendra is 13 years old, so we can write the equation as:
Kendra's age = Justin's age / 2
13 = A / 2
Now, we need to solve for the variable A to find Justin's age.
To isolate A, we can multiply both sides of the equation by 2:
2 * 13 = A / 2 * 2
26 = A
Therefore, Justin's age, represented by A, is 26.
Among the given answer choices, the equation that represents Justin's age is:
C. 2A = 13
