It is given that yvaries directly as x. If y= 5 when x= 4 determine the constant of variation,

Step-by-step explanation:

Given that,

y varies directly as x. It means,

y = kx

Where

k is the constant of variation

or

So, the constant of variation is .

step-by-step explanation:

20% of 120 is 24. if you subtract 24 from 120 you get 96

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
