The numbers r and s vary directly and the constant of variation is 3/5.Find r if s=45;and find s if r=33.?

Answer 1

r = ks
r = (3/5)s
r = (3/5) x 45
r = 37

r = ks
s = r/k
s = 33/ (3/5)
s = 33 x 5 /3
s = 55

Answer 2

formula for constant of variation
xy=k

therefore rs=3/5
then
(45)r=3/5
so then take 3/5 and divide it by 45 to give you r
r= .13 (rounded)

for s
33s=3/5
divide 3/5 by 33
s= .018(rounded)

Answer 3

r = k*s
r = 3/5 * s ----(1)

from eq(1) when s = 45
r = 3/5 * 45 = 27

from eq(1) when r = 33
33= 3/5 * s
s = 55
