User: Jocelyn has test scores of 75, 83 and 91 on her first three Algebra tests. What will she need to score on her 4th test so she will have a average of 85?

Weegy: 91 is the correct answer. [ Solution: (75+83+91+x)/4 = 85 249+x = (85x4) x = (85x4)-249 x = 340-249 x = 91 ]

(x^-2 y)/y^-5 = y^5/(x^2 y) = y^4/x^2

(12x^3 + 18x^2 - 3x ) divided by 3x is 4x^2+6x-1.
(12x^3 + 18x^2 - 3x )/3x
=12x^3/3x+18x^2/3x-3x/3x
=4x^2+6x-1.
