AE is about half of AC. What I did was get half of 28, which is 14, and represented one of the numbers.
3 x 7 = 21 - 7 = 14
It is D.
(I don't know for sure if this is right, but I did the best I could)
There are 20 cassettes.
Step-by-step explanation:
Given,
Ratio of cassette to compact disc = 10:3
Let,
the number of cassettes = 10x
Number of compact disc = 3x
According to given statement;
the number of cassettes is 10 less than 5 times the number of compact discs.
10x = 5(Number of CD) - 10
Dividing both sides by 5
Number of cassettes= 10x = 10(2) = 20
There are 20 cassettes.

Answer:
f(g(3)) = 24
Step-by-step explanation:
Evaluate g(3) then substitute the result obtained into f(x)
g(3) = 3³ = 27 , then
f(27) = 27 - 3 = 24
4:00 because there are 60 minutes in an hour and 35+25=60 or 1 hour
