I don't know what is between f(x) and g(x), so (for now) there are two posible answers:
1.

- function multiplication:

2.

- function composition:
(4/9)/x= 12
Multiply both sides by x
4/9=12x
Divide both sides by 12
(4/9)*(1/12)= 4/108
4/108= 1/27
Final answer: 1/27
What do you mean? Please message me the question and I will gladly help
I’m not *completely* sure if this would be right, but it could possibly be:
160
how i got this:
20 = 150
/(divide) 150
0.13(recurring) = 1
x1200
160 = 1200
if you need me to explain anything in detail, please feel free to message! have a nice day:)<3
