Answer: They are inverses of each other
==========================================================
Explanation:
We'll need to compute h(f(x)) and f(h(x)) to see if we get x each time.
and,
Both composite functions lead to x each time.
The equations h(f(x)) = x and f(h(x)) = x being true means each function is the inverse of the other.
29.37 rounds to 29
109.96 rounds to 110
---------------------------
The rule is that if the decimal portion is 0.50 or higher, then you round up. Otherwise you round down.
R^3 * X
(=) 5^3 * 6
125 * 6
750
The distributive property of 75/3 may look like:
75/3 = 30/3 + 30/3 + 15/3
It's easier to count 30/3 than 75/3, so I did it twice and then I had 15 left, because 75 - (30 + 30) = 15.
That's basicly how you do it - just try to find the easiest number to divide (smaller then the given dividend).
