Answer:
11. -42
12. 9
13. 100 + (-100) = 0
14. 6 + (-4) = 2
Step-by-step explanation:
11. -42 + 36 would be the same as 42 - 36 but in this case it's negative, so that would be -6.---- -6 + (-36) equals -36 minus 6, or -42 (a negative plus a negative is always a negative)
12. -17 + 17 = 0 , 0 + 9 = 9
13. since the hawk started at 100 ft, add (-100) to get 0 (ground level)
14. leah ran 6 blocks north, then 4 blocks south, so add 6 + (-4)
