1/3 cup of blue paint with 1/2 of red paint. How many cups of blue and red paint does Jessica need to make 20 cups of her favorite purple paint?

The answer is A cuz all u have to do is solve for x by moving the 60 to the other side of the equation like this: 5x^2=60 then you divide 5 from both sides to leave the x^2 alone like this: 5x^2/5=60/5 then you should get: x^2=12 then u square root it and get 2isqrt3, -2isqrt3 (sqrt is square root)
