For this case we have the following solution.
 x = gallons of water to be added
 For the 10% solution we have:
 0.1 * 8 = 0.8
 Then, for 5% we have:
 (0.8 / x + 8) = 0.05
 Rewriting:
 (0.8 / x + 8) = (5/100)
 Answer:
 An equation can be used to find x, the humber of gallons of water he should add is:
 (0.8 / x + 8) = (5/100)

Let f(x) = 2x – 1, g(x) = 3x, and h(x) = x2 + 1. Compute the following.
yaroslaw [1]
4. Since f(x) = 2x - 1, we are looking for h(2x - 1), which is (2x-1)^2 + 1. By tha time you expand this you'll get, 4x^2 - 4x + 2. So that is the answer.
5. f(f(x))  = f(2x - 1) = 2(2x - 1) - 1 = 4x - 3
6. h(g(x)) = h(3x) = (3x)^2 + 1 = 9x^2 + 1
