Question

x varies directly as y and x =25 when you = 75. find x, when y is 225

Direct and inverse variation? ​

Answer 1

Direct variation

x = 75

Step-by-step explanation:

x/y = 25/75 = 1/3

THEREFORE

constant of proportionality = 1/3

If y = 225

Then x = 225 × 1/3 = 75

Answer 2

Answer:

75

Step-by-step explanation:

****

x is directly proportional to ytherefore x = kywhere k is constant****

given,

x=25

when,y=75

28 = k*75

therefore k = 1/3

now to find = x = ?

we know

y= 225

k= 1/3

therefore

x = 225*1

3

therefore,

x = 75
