Quick: donald solved 5 morr mathcounts problems than janet. janet solved 3 more than ann. ann solved twice as many as randy. if randy solved 7 problems, how many problems did donald solve? (3-5 sentence explanation of how you got your answer in steps)

Here's how I like to represent this:

Randy = 7

Randy * 2 = Ann

Ann + 3 = Janet

Janet + 5 = Donald

If we go along and fill in the blanks for each equation, we do this:

7 * 2 = 14

14 + 3 = 17

17 + 5 = 22

So Donald solved 22 problems.

Hope this helps!

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
