Answer:
1/2
Step-by-step explanation:
we know that 1/4 of them failed, meaning that 3/4 of them passed.
1/3 of 3/4 is 1/4, meaning that 1/4 of the class got an A.
If 1/4 failed, and 1/4 passed with an A, that leaves 2/4 of the class that passed but didnt get an A, which simplifies to 1/2.

-5x-36+8x
3x-36
3(x-18)
(x+3)(4x−2) = 4x2+10x−6
(x+2)(x2−3x +4) = x3−x2−2x+8
Add 42 to both sides.
Add 3 and 42 to get 45.
Divide both sides by -3. As -3 is <0, the inequality direction has changed.
Divide 45 by -3 to get -15.
