Answer:
The number of words per page.
Step-by-step explanation:
We're given the time per page. The book could have 10 words or it could have 1,000 words. We wouldn't know until given that information.
I think maybe either how many pages are there or how many words are on each page.
x = 5
4x + 3 = 23 ( subtract 3 from both sides )
4x = 20 ( divide both sides by 4 )
31 cups
62 x 1/2 = 31
13
8--5 = 8 + 5 = 13
