x = 9
-------------------
(2*9 : 3) + 1 = 7
6 + 1 = 7
Answer:
D. 2
Step-by-step explanation:
Common denominator is already presented which is 4.
-3/4 and 3/4 cancel each other out.
you can also convert to decimal form -3/4 + 2 3/4 is the same as:
-0.75 + 2.75 = 2.
-33/12. Lets forget the negative symbol.
12 goes into 33, 2 times with 9 remaining.
So now get the negative sign back.
It will be -2 9/12 but you can reduce that to -2 3/4.
Hope this helps :)
