Answer
Arlie is 12 years old.
Solution
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.

To express the relationship between Arlie and Ava in a number sentence, you can use the equation: Arlie's age = Ava's age + 3. Since Ava is 9 years old, the number sentence would look like this: A + 3 = 12, where A represents Ava's age. To find Arlie’s age, simply add 3 to Ava’s current age: 9 (Ava's age) + 3 = 12. This means Arlie is 12 years old, showcasing a simple solution using age relationships!
