Let's break this down step by step:
- Identify Reiki's age: Reiki is 6 years old.
- Understand the relationship: Rachel is 3 years more than twice Reiki's age.
- Calculating twice Reiki's age: Since Reiki is 6, we calculate twice his age as follows:
Twice Reiki's age: 2 * 6 = 12. - Add 3 years: Now we need to add 3 to that result (12):
12 + 3 = 15.
So, Rachel's age is 15 years old. We can also write a number expression for Rachel's age as:
Rachel's age = 2 * (Reiki's age) + 3 = 2 * 6 + 3
This means Rachel's age can be expressed as 15.
