is four eigths greater than four tenths

I'm tryin to write an essay about A Day in the Life of a Pencil... but I'm not sure how to start it. HELP!

Math
The function g and h are defined by g(x) 4x+1/3x-2 and h(x)5x-2 Calculate g(0) 4(0)+1/3(0)-2 = -1/2 Calculate h(1/5) 5(1/5)-2 = -1 Determine the value of gh(1/5) 4(5(1/5)-2) (3(1/5)-2)= 4(-1/-1.4)= 2.85 is this right??

Math
So the ans would be 28-3x.

Math (is this correct)
The functions f and g are defined by: f:x 3x+1 g:x 9-x Determine an expression for the function gf(x) 3(9-x)+1 27-3x+1

math (how do i solve the last part)
The functions f and g are defined by: f:x 3x-2 g:x 2x+5 Evaluate:g(-6), fg(3) g(-6)= 2(-6)+5= -7 fg(3)= 3(2x+5)-2 6x+15-2 6(3)+13 = 31 Evaluate f(x)=8, calculate the value of x
