x +12 -sqrt(x) = 42

-sqrt(x) = -x+30

-sqrt(x)^2 = (-x+30)^2

x^2 - 61x + 900 = 0

(x-36) (x-25) = 0

 x = 36

36+12 = 48 - sqrt(36) = 48-6 = 42

 X  = 36

There are 52 colas and 26 lemon-lime sodas in the cooler. What is the ratio of colas to lemon-lime sodas?
sergejj [24]
Hi there.

If there are 26 lemon-lime sodas and 52 colas, then that means our ratio is going to be 52:26; however, this is not simplified as both of these are even numbers. To simplify, divide both of these numbers by 26.

26 / 26 = 1
52 / 26 = 2

Our new and simplified ratio of colas to lemon-lime sodas is going to be
2:1.

I hope this helps!
