If d varies inversely as t, and d = 20 when t = 2, what is the value of t when d = -5?

OpenStudy (cwrw238):

d = k/t where k is a constant to be found k is found by plugging in the given values of d and t and solving for k insert the value of k into the original formula and plug in d=-5 to find t

OpenStudy (anonymous):

okay so you do 20 x 2 to get 40

OpenStudy (cwrw238):

right so rewrite the formula with k = 40
