Hey there! :D
Find 10% of 85.
10%=.10
85*.10= 8.5
Add that to 85.
85+8.5= 93.5
We could also see if this 10% error is in the other direction.
85-8.5= 76.5 <== this is not an answer choice
So, we know it must be "A" 93.5 C
I hope this helps!

Answer:
23
Step-by-step explanation:
Simplify the following:
(-66)/(-3) - 4 - -5
The gcd of -66 and -3 is -3, so (-66)/(-3) = (-3×22)/(-3×1) = (-3)/(-3)×22 = 22:
22 - 4 - -5
-(-5) = 5:
22 - 4 + 5
22 + 5 = 27:
27 - 4
| 2 | 7
- | | 4
| 2 | 3:
Answer: 23
Answer:
Q= 126°
Step-by-step explanation:
Using the picture given, because these are parallel lines broken by a transversal, we can say the following
M=A=Q=F
B=C=D=G
Since, for example, M and C are the same line, we can say that M+C=180 and so on.
M=Q
Q= 126°
Subtract 79 from both sides to isolate variable b.
b = 159 - 79
b = 80
