Keira’s age is half the age of Justin Keira is 13 years old which of the following equation represents Justin’s age A
13a = 2
2a = 13
1/2 a = 13
a + 1/2 = 13
What’s the correct answer?
The correct equation that represents Justin's age is: 2a = 13
The correct equation that represents Justin's age is:
2a = 13
This equation shows that Justin's age is twice Keira's age, which is consistent with the given information that Keira's age is half the age of Justin.
The correct answer is A. 13a = 2.
To solve this problem, we are given that Keira's age (K) is half the age of Justin (J). Keira is 13 years old, so we can write this information as the equation K = 13.
Since Keira's age is half the age of Justin, we can represent Justin's age as 2 times Keira's age. Therefore, Justin's age (J) can be written as J = 2K.
Substituting the value of K from the first equation into the second equation, we get J = 2(13). Simplifying this equation, we get J = 26.
So, Justin's age can be represented as 13a = 2, which is option A.
