Answer: They are inverses of each other
============================================================
Explanation:
We need to check two things:
If both of those equations are true, then f and g are inverses of each other.
----------------
Part 1

So far, so good. Now we need to check the other equation mentioned.
------------------
Part 2

That works out as well. Both equations mentioned are true, which confirms the two original functions are inverses of one another.
Answer:
3.24 kg
Step-by-step explanation:
internal Vol = (30-0.5)(16-1)(17-1) = 7080 cm^3 = 7.08ltrs
external Vol= 30* 16* 17 = 8160cm^3 = 8.16ltrs
Vol of thickness = 8160 - 7080 = 1080cm^3
Mass of the tank= density * volume = 3*1080 = 3,240g = 3.24 kg

Let the number=x
double=2x
add 6
2x+6
divide by 2
(2x+6)/2=x+3
subtract 3
x+3-3=x
which is the original number
(2x+6)/2-3=x+3-3=x
