Danica has 15 stickers. she gives 3 to one friend and gets 4 from another friend . what expression would match the words?

(s equals he final number of stickers)

There are two different expressions that can relay to this problem.  (15-3)+4=s, or you can just write it explicitly: (15-3)+4= 16 stickers.  

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good

Don’t know sorry about that
