Given: q = 7m + 3n, r = 11 - 2m, s = n + 5, and t = -m - 3n + 8.
simplify r - s + t.
m - 2n - 2
-m + 2n - 2
3m - 4n + 14
-3m - 4n + 14

is there any photos or whatever?

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
