Kendras age is half the age of Justin Kendra is 13 years old which of the following equations represents Justins age a

Answer 1

If Kendra is 13 years old and her age is half of Justin's age, we can represent Justin's age (J) with the following equation:

\[
Kendra's \ Age = \frac{1}{2} \times Justin's \ Age
\]

Given that Kendra is 13 years old, we can substitute her age into the equation:

\[
13 = \frac{1}{2} \times J
\]

To solve for Justin's age (J), multiply both sides of the equation by 2:

\[
J = 2 \times 13
\]

Thus,

\[
J = 26
\]

The equation representing Justin's age is:

\[
J = 2 \times 13
\] or equivalently,

\[
J = 2K
\]

where \( K \) is Kendra's age.
