Answer:
Alvin: 49
Elga: 40
Step-by-step explanation:
- The equation is 89 = x + (x-9).
- Remove the parenthesis and combine the like terms. 89 = 2x - 9
- Add 9 on both sides. 98 = 2x
- Divide by 2 on both sides. x = 49
- 49 is the age of Alvin. (49-9) 40 is the age of Elga.

The answer to the question is 12.875
The discounted clock would be 6 dollars. I found this by creating a table with 3/3, 2/3, and 1/3 on one side and the 18 across from 3/3 since it is the regular price. To find 2/3 I think we should find 1/3 first. To find that we simply divide 18 by 3 since we are finding one third of 18. Luckily 3 evenly goes into 18 6 times. Now we aren’t done, that is 1/3 so we double the 1/3 which is 2/3 and we double the 6 which is 12. Now that we know how much those cost, it says 2/3 off. The regular price was 18 and 2/3 was 12 so 18-2/3 is 18-12 which equals 6. The discounted alarm clock is $6.00.
