82*
Step-by-step explanation:
10x+8 = 12x-10
18 = 2x
X=9
Angle 1 = 98*
Angle 3 = 98*
180 - 98* = 82*
If 12 donuts cost $8.50, you can divide $8.50/12 donuts (presumably with a calculator) to get $0.7083/donut which rounds to $0.71/donut. Make sense?

The answer is D because 6 3/4 in an improper fraction is 27/4. 5 1/2 in an improper fraction is 11/2. If you want to add 27/4 and 11/2, then you have to multiply both the numerator and denominator of 11/2. Now, 11/2 will be turned into 22/4. 27/4+22/4=49/4. Now, you have to turn 2 1/4 into an improper fraction to subtract. 2 1/4 will be turned into 9/4. 49/4 - 9/4=40/4. 40/4 is simplified to 10. So the answer is, D.
