A quantity, T , Varies inversely with a quantity, r. If t=6 then r=5 what is the constant of variation

t varies inversely to 30/r

Step-by-step explanation:

t varies inversely to r

(lol I can't seem to find the variation sign in the keyboard)

when you introduce the constant K the sign changes to =

t=k/r

if t=6, r=5

substitute the values

6=k/5

k= 6×5

k=30

we have found the constant so we add it to our initial equation

t inversely varies to 30/r
