Answer 1

Answer:

5. -11+7+X = 15

X= 15+11-7

X= 19

6. sum of -7 and -16

-7+(-6) = -13

sum of 3 and -8

3+(-8) = -5

sum of -13 and -5

-13+(-5) = -18

7. sum of -4 and 6

-4+6 = 2

sum of -8 and 5

-8+5 = -3

subtract 2 from -3

2-(-3) = 5

8. sum of -9 and 15

-9+15 = 6

sum of -15,-2 and 14

-15+(-2)+14 = -3

add 6 and -3

6+(-3) = 3
