Five cupcakes cost $7. How much is 7 cupcakes worth?
$9.80
What is (-8)5/3
-32
(x+1)(2x-5)
2x2 - 3x - 5
Solve for x: (3-x)/2 = -2
x=7
125-2/3
1/25
Factor (2x2 - 10x +8)
2(x -4)(x - 1)
-5x + y = 10 and 3x - 2y = 1. Solve for both variables.
x = -3, y = -5
Simplify (125 x3 y6)4/3
625 x4 y8
Factor x4 - 3x3 - 4x + 12
(x-3)(x-2)(x+2)
Solve 2x - 3y = 5 & 3x + 3y = -1
x = 4/5, y = -17/15
Simplify (4 y2)-1/2 / (2 x-1)
x / (4 y)
(x-1)(x+1)(x-3)(x+3)
