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
1/2a = 13
13a = 2
a + 1/2 = 13a
2a = 13
The equation that represents Justin's age, a, is:
2a = 13
The correct equation representing Justin's age, a, is:
2a = 13
To solve this problem, we need to set up an equation based on the given information.
The equation that represents Kendra's age being half the age of Justin would be:
Kendra's Age = 1/2 * Justin's Age
Since Kendra is 13 years old, we can substitute her age into the equation:
13 = 1/2 * Justin's Age
To find Justin's Age (represented by the variable 'a'), we can solve this equation by multiplying both sides by 2:
2 * 13 = 1/2 * Justin's Age * 2
26 = Justin's Age
So, the equation that represents Justin's age, a, is:
a = 26
Therefore, the correct equation from the given options is:
2a = 13
