Marcia is 3 times as old as kate. the difference between their ages is 12 years. find the age of each

Kate's age is 6. Marcia's age is 18.

Step-by-step explanation:

Let Kate's's age = k

Marcia is 3 times older, so Marcia's age is 3k.

The difference in ages is 3k - k.

We are told the difference in ages is 12, so

3k - k = 12

2k = 12

k = 6

Kate's age is 6.

3k = 3(6) = 18

Marcia's age is 18.

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
