Let x = number of problems on test
If he got 14 wrong, then x - 14 is the number correct.
x - 14 = .72x
.28x - 14 = 0
.28x = 14
x = 50
The test consisted of 50 problems.
Answer:
3 1/2
Step-by-step explanation:
if you multiply 4 and 3 you 12 if you multiply 1/2 times 3 you get 1 1/2 and 1 1/2 + 12 = 13 1/2 and then you have to find a fraction that when multiplied by 4 1/2 you get 2 1/4 and 4 1/2 × 1/2 = 2 1/4 so 2 1/4 + 13 1/2 = 15 3/4

Answer:
f(x)/g(x) = 4x^2+6x-3 remainder -12
or
f(x)/g(x) = (4x^2+6x-3)/(2x+1) + (-12)/(2x+1)
or
((4x²+6x-3)-12)/(2x+1)
Step-by-step explanation:
f(x)= 8x³ + 16x² -15
g(x) = 2x+1.
Using long division,
f(x)/g(x) = 4x^2+6x-3 remainder -12
