9) If the positive integer x leaves a remainder of 2 when divided by 8, what will the remainder be when x + 9 is divided by 8?

1. 0
2. 1
3. 2
4. 3
5. 4

The easiest way to get the answer here is to pick numbers. Pick a number for x that has a remainder of 2 when divided by 8, such as 10. Increase the number you picked by 9. In this case, 10 + 9 = 19. Now divide 19 by 8, which gives you 2 remainder 3. Therefore, the answer is 3.
