melomori [17]
F(x) = 4x + 8

Find x in terms of f(x):-

4x = f(x) - 8
x = (f(x) - 8 )  /  4

replace x by h(x) and f(x) by x

h(x) = (x - 8 ) /4

What is 15 1/5 + 3 5/8 ?
guajiro [1.7K]

The Answer is 750/40 = 18 33/40

To get this answer you have to find the LCM which in this case is 40 and then multiply to make it into that fraction(multiply both number, and numerator, and denominator) then add. When you add these you get 750/33 and then you have to simplify by dividing and you get 18 33/40
