Answer:
21
Step-by-step explanation:
First, we would find 30% of 30, which would be 9. Then we would subtract 9 from 30 because we are decreasing it by 30%. That means the answer is 30-9, which is 21.
Answer: C
Step-by-step explanation:
If you want to survey 100% of the students, and 20% has been already surveyed, 200 students would chose pop as their favorite genre of music because 41 x 5 = 205, which is closest to 200.
If f(x) = 2x + 7 & g(x) = 7 - x
then:
fog = 2(7 - x) + 7
= 14 - 2x + 7
= 21 - 2x
gof = 7 - (2x + 7)
= 7 - 2x - 7
= -2x
gog = 7 - (7 - x)
= 7 - 7 + x
= x
