the average of 2 number is 9. list all possible of numbers that will work

8, 10 will work. what about 9,9? what about 0,18?

8,10 9,9 0,18. That's my sugggeston.

To determine all the possible sets of numbers that have an average of 9, we need to consider different combinations of numbers that sum up to 18 (since the average of two numbers is equal to their sum divided by 2).

Let's create a list of all the possible pairs of numbers that add up to 18:

1 + 17 = 18
2 + 16 = 18
3 + 15 = 18
4 + 14 = 18
5 + 13 = 18
6 + 12 = 18
7 + 11 = 18
8 + 10 = 18
9 + 9 = 18

There are 9 possible combinations:

1. (1, 17)
2. (2, 16)
3. (3, 15)
4. (4, 14)
5. (5, 13)
6. (6, 12)
7. (7, 11)
8. (8, 10)
9. (9, 9)

These are all the possible sets of numbers that will give an average of 9.
