Question

The teacher told her students that her age is "8 more than a, times 2." Write an expression to show the teacher's age.

Answer 1

16 + 2a

Explanation:

1. Since "a" is the missing variable, we need to set up an equation to express this.
2. It says, "8 more than a" which means we add 8 to a.
3. So far we have 8 + a = ?
4. It says "times 2" so we multiply the expression "8 + a" by 2.
5. Now we have 2(8 + a)
6. We can reduce this by using distributive property.
7. 16 + 2a
