Answer:
Step-by-step explanation:
First you do the division in parentheses and you get (-3/4*8/1) = -24/4 = -6
The new exercise becomes 2/3 *(-6)*1/3
Next, since there are only multiplication we have to do then in order from left to right so we have
-12/3*1/3 = -12/9
We can simplify by 3 and we get -4/3
Anwer choice C
Answer:
C = 17/7 or 2 3/7
D = -4/7
Step-by-step explanation:
3C+4D=5
2C+5D=2
2C = 2 - 5D
C = 1 - 2.5D
3(1 - 2.5D) + 4D = 5
3 - 7.5D + 4D = 5
-3.5D = 2
D = -4/7
C = 1 - 2.5(-4/7)
C = 1 + 10/7 = 17/7
