Use Order of Operations to Solve -2 – (7- 3) ÷ 4 -2 – (4) ÷ 4 -2 – 1 = -3

Simplify each expression (5x 3) – 4x + 7 = 15x – 4x + 7 = 11x + 7

Evaluate each expression a = 1, b=7, and c = -2 3a + ab – c = 3(1) + 1(7) - -2 = = 12

Use replacement set to solve

Determine whether each pair of ratios forms a proportion.

Solve for x. -5 = x + 9 X = -14

Solve for x. x + (-4.2) = 8.6 X = 12.8

Solve for x. x + (-5) = -2 X = 3

Solve for x. X – (-⅝) = ¾ X = ⅛

-4a – 1 = -1 -4a = 0 a= 0

-2t + 4 = 10 – t -t = 6 t = -6

11 = ½ b – (-3) 8 = ½ b 16 = b b = 16

-2( t -2) = 10 – t -2t + 4 = 10 – t -t = 6 t = -6

Solve the ratio

Solve abstractly 7x – c = b Solve for x. 7x = b + c x = b + c 7
