1) times = multiply, decreased = subtract ∴ 5x - 3
2) divided = division, increased = add ∴ [tex]\frac{x}{3}[/tex] + 2
3) more than = add, product of x and y = multiply ∴ 3 + 4x
4) less than = subtract, times = multiply ∴ 7x - 2
5) per hour = for every hour, so multiply ∴ 8x
6) decreased = subtract ∴ x - 2
7) there are x students per class, so multiply ∴ 6x
8) as many = multiply ∴ [tex]\frac{2}{3}[/tex]x
9) twice = multiply by 2, increased = add ∴ 2x + 5
10) less than = subtract, product of x and y = multiply ∴ 15x - 9
