Answer:

  x = 48

Step-by-step explanation:

It looks like your proportion is ...

  y = k√x

Then k can be found as ...

  k = y/√x = 25/√3

__

For y = 100, the value of x can be found from ...

  100 = (25/√3)√x

  4√3 = √x . . . . . . . . . . multiply by √3/25

  48 = x . . . . . . . . . . . . . square both sides
