Question

Three times danniele’s age, d, minus 2 years is less than her brother’s age of 31. What is the maximum that Danniele’s age could be?

Answer 1

10

Explanation:

First write out the equation

3d - 2 < 31

Add 2 to both sides

3d < 33

divide both by 3

d < 11

So the maximum age that Danniele could be has to be less than 11

10 is the maximum age that She can be

Answer 2

Answer: 3d - 2 ≤ 31

(Her max. age is 11)

Explanation:

Add two to each side.

3d ≤ 33

Divide by three.

d ≤ 11

*HER MAXIMUM AGE IS 11*
