Answer:
x = 45
Step-by-step explanation:
The angles are supplementary
(2x + 40) + (3x - 85) = 180
Combine like terms
5x - 45 = 180
Add 45 to both sides
5x = 225
Divide both sides by 5
x = 45

Since 0.8 is less than 1, you can cross out every fraction greater than 1. If the numerator(top number) is greater than the denominator(bottom number), it is greater than 1
_____________________________________________________________
You can cross out 12/7 because it is greater than 1.
That leaves you with 3 choices.
_____________________________________________________________
Now, divide the numerator by the denominator to change all 3 fraction to decimal.
_____________________________________________________________
7 ÷ 8 = 0.875
3/6 = 0.5
4/5 = 0.8
A. 12/7 x
B. 7/8 x
C. 3/6 x
D. 4/5 <span>✔
Your answer is the last choice.
Hope this helps :)</span>
