me with this last minute math i can't remember a guy out lol.

1. the formula rt = d is used to calculate distance if you know the rate and time. what is the equation for finding the time when given the rate?

(a) rd = t
(b) d/r = t
(c) r = td
(d) r/d = t

2. the formula for finding the perimeter of an equilateral triangle is p = 3s. how can you transform the formula so that it can be used to determine the length of one side of the triangle when given perimeter

(a) 3p = s
(b) p/s = 3
(c) ps = 3
(d) p/3 = s

5 stars and if your right.
