UpStudy AI · Accepted Answer

To express the relationship between Arlie and Ava in a number sentence, we can define the ages of both individuals using variables.

1. Let $$ A $$ represent Ava's age.
2. Let $$ R $$ represent Arlie's age.

From the problem, we know:
- Ava's age $$ A = 9 $$
- Arlie is 3 years older than Ava, which can be expressed as $$ R = A + 3 $$

Substituting Ava's age into the equation gives us:
$$
R = 9 + 3
$$

Thus, the number sentence that represents the relationship is:
$$
R = 12
$$

This means Arlie is 12 years old.
Arlie is 12 years old.
