Question

3. x varies directly as y and x = 25 when y = 75. Find x, when y is 225.
​

Answer 1

Answer:

75

Step-by-step explanation:

when X= 25 y= 75

then X=25 y = 3x25

so we can say above equation

y=3X

X=y/3

X = 225/3

X= 75

Answer 2

Answer:

75.

Step-by-step explanation:

If x= 25 when y= 75 then it means that 3x=y.

so, if y=225, then x=

$\frac{y}{3} = \frac{225}{3} = 75$
