Step-by-step explanation: The median is the number in the middle sorted from least to greatest, here 21 is the middle number.
3 years ago:
m - 3 = 3(b - 3)
m - 3 = 3b - 9
m + 6 = 3b
m/3 + 2 = b
5 years from now:
m + 5 = 2(b + 5)
m + 5 = 2b + 10
m - 5 = 2b
m/2 - 5/2 = b
combine:
m/3 + 2 = m/2 - 5/2
1. multiply by 6
2m + 12 = 3m - 15
2. add 15 - 2m to both sides
27 = m

Well, input and output are the functions so look up how to do functions with input and output and you will get the answer or look at this picture
Write 90 out of 120 as a fraction-90/120. Simplify that until you can't any more and you get 3/4 of the original price.
-3, -1, 1, 3, 5 would be five of them.
