Hello from MrBillDoesMath!
Answer:
x > -7/3
Discussion:
-3x + 8 < 15 => add 3x to both sides
(-3x + 3x) + 8 < 15 + 3x => (-3x + 3x) = 0
8 < 15 + 3x => subtract 15 from both sides
8-15 < 3x => 8 - 15 = -7
-7 < 3x => divide both sides by 3
-7/3 < x
Thank You,

The correct answer is 14.2 lb which is choice D.
Let:
F = minimum force required to prevent ball from rolling down the ramp
The formula will be:
F = w * sin theta
F = w * sin (39 degrees)
F = 22.6 * sin (39)
= 14.2 lb (this is rounded to the nearest tenth)
12 times 4 minus 3 because the 12 represents how much is in each of the 4 cases and you minus that by 3 and you get your answer
