Question

Find the missing value. y is directly proportional to x and inversely proportional to the square of z. y = 20 when x = 50 and z = 5. Find y when x = 3 and z = 6.

Answer 1

i know this equation is x=y/z

Answer 2

so this is 2 parts

directly proportional

y = kx

substitute y = 20 and x = 50 to find k

now the inverse proportion

y = k/z^2

to find k, substitute y = 20 and z = 5

they you can complete the rest of the question

Answer 4

would this be 20=k/25?

Answer 5

(20*25)=k

Answer 6

that's correct
