Carly is 3 times her brother's age.
the sum of their ages is no more than 24 years.
enter an inequality that can be used to represent this situation in the first box, where x represents carly's brother's age.
enter the oldest age carly's brother can be in the second box.

-- im having a very hard time with this, but for oldest age is 9? ?

If we let x represent the age of Carly's brother, then Carly's age would be 3(x) since he's thrice as old. To find the sum of their ages, we just combine the expressions and come up with x + 3x = 4x. We know that the sum of their ages is not more than 24 years. Hence, we can write an equality showing this relationship as shown below. 4x ≤ 24 x ≤ 6 From this, we can see that the oldest age possible for Carly's brother would be 6. 4x ≤ 24 | 6 years old
