Answer:

Step-by-step explanation:
Let the first unknown integer be x
Let the second unknown integer be y

d.16 because
-4 to the second power would be -4 times -4 and (negative times a negative equals a positive) so 4 times 4=16 which is the same as -4 times -4.
15.5% is the same as 15.5/100 or 155/1000, which you can take a 5 out of.
After that, you will get 31/200
|-7+6 | |-7| + 6
|-1| 7+6
