Answer:
(8 (-1))
Step-by-step explanation:
Simplify the following:
8 (7 + 4×2 - 4 (11 - 7))
11 - 7 = 4:
8 (7 + 4×2 - 44)
4×2 = 8:
8 (7 + 8 - 4×4)
-4×4 = -16:
8 (7 + 8 + -16)
7 + 8 = 15:
8 (15 - 16)
15 - 16 = -(16 - 15):
8 (-(16 - 15))
| 1 | 6
- | 1 | 5
| 0 | 1:
8 (-1)
8 (-1) = (8 (-1)):
Answer: (8 (-1))
Answer:
I do believe that your correct anwer is D.
Step-by-step explanation:Hope it helped
If you move the decimal point the same number of places in the dividend and the divisor, you are multiplying them both by the same power of 10. That does not change the quotient.
