Answer:
A and B
Step-by-step explanation:
C) 9 7/8 - (- 2 4/5) - (- 1/2) =
= 9 7/8 + 2 4/5 + 1/2 (F)
D) - (- 9 7/8 + 2 4/5) - 1/2) =
= 9 7/8 - 2 4/5 - 1/2 (F)
E) 9 7/8 - (- 2 4/5 - 1/2) =
= - 7/8 + 2 4/5 + 1/2 (F)
-x - 5y = 16
2x + 5y = -7
(add)
x = 9
(2 × 9) + 5y = -7
18 + 5y = -7
- 18
5y = -25
÷ 5
y = -5
I hope this helps!
