The answer is D. The grand total for 12th graders is 68. Divide the 28 students in 12th grade who prefer math by the grand total to get you a rounded answer of 0.412.
Answer:
Number 2 is 10 dollars and 17 cents
Number 1 is 194 dollars and 2 cent
Step-by-step explanation:
T=D/R
You must isolate T so you divide R on both sides. This isolates T and gives you the answer.
(f + g)(x) is equal to f(x) + g(x).
So (f + g)(x) = (3x + 5) + (-2x^2 - 5x + 3) = -2x^2 - 2x + 8
which is choice C.
