Answer:
The score that separates the top 59% from the bottom 41% is 31.68
Step-by-step explanation:
To convey as an algebraic expression simply break down the statements and use any variable to represent the number in the sentence.
10 • x^2 = 40x
10x^2 = 40x
10x^2 - 40x = 0
10(x^2 - 4x) = 0
X(x - 4) = 0
X = 0
X - 4 = 0
X = 4.
Here are two possibilities of what the number can be, but because it is a nonzero number, I believe it would be 4.
8x + 2 + 70 + 60 = 180
8x + 132 = 180
180 - 132 = 48
48/6 = 6
X = 6
