Answer:
x = 8.5
Step-by-step explanation:
4x-5=9+20 (evaluate right side)
4x - 5 = 29 (add 5 to both sides)
4x = 29 + 5
4x = 34 (divide both sides by 4)
x = 34/4
x = 8.5
So the 74% that you have right now is the other 80% of your grade. So you multiply it by its weight and solve for the other one making it equal to 78%.
(.74)(.8) + (.2)(x) = .78
.592 + (.2)(x) = .78
(.2)(x) = .188
(x) = .94
So, you need to get a 94% on your final test.
