-9.1 - |-7.5| =-9.1-7.5=-16.6. The absolute value is positive, but then it is subtracted.
Question 2: 4x2 + 2 when x = 2. 4*(2)^2+2=18
Question 3: (5 - x)/6 when x = 3. (5-3)/6=(2/6)=(1/3)

1)
-9.1-abs%28-7.5%29=-9.1-7.5=-16.6
.
2)
This equation is not clear. My best guess:
Substitute 2 for x:
4x%5E2%2B2=4%282%29%5E2%2B2=4%284%29%2B2=16%2B2=18
.
3)
Substitute 3 for x:
%285-x%29%2F6=%285-3%29%2F6=2%2F6=1%2F3
