I'm trying to review for my upcoming TEAS test, so I'll probably be on here a lot the next few days. I'm going over some practice basic algebra questions. I'm having problems with this one.. If Lynn can type a page in p minutes, what piece of the page can she do in 5 minutes? The answers they give are...
A. 5/p
B. p - 5
C. p + 5
D. p/5
E. 1- p + 5
Their answer and explanation is..
A: The following proportion may be written: 1/p=x/5. Solving for the variable, x, gives xp = 5, where x=5/p. So, Lynn can type 5/p pages, in 5 minutes.
I can't figure out how they got from 1/p=x/5 to xp = 5?
