3/4 w = 9
multiply by 4/3 on both sides
4/3 x 3/4 w = 9 x 4/3
w = 9 x 4/3
Simplify that
w = 3 x 4
w = 12
So your final answer is
I would say the answer is C
<span>RULE #1: you can
add, subtract, multiply and divide by anything, as long as you do the
same thing to both sides of the equals sign. ... <span>RULE
#2: to move or cancel a quantity or variable on one side of the

The four number u could be is 2
Answer
f(x)=8/x, g(x)=8/x
f(g(x)) = f(8/x)=8/<span>8/x=x,
</span>g(f(x)) =g(8/x) =8/<span>8/x=x,
so </span>f(g(x)) = g(f(x)) = x. if <span>f of x equals eight divided by x and g of x equals eight divided by x</span>
