Solving Expressions Equations Inequalities

Choose an expression that is equivalent to the following
6n + 2(3 - 5n)

• n + 6

• 6 - 4n

• 16n + 6

Choose the first step in solving the following equation.
-3y - 12 = 14

• add 3 from both sides

• add 12 to both sides

• subtract 12 from both sides

0.1( x - 20 ) > 2

• x > 40

• x < 40

• x > 220

Which expression is equivalent to (s - 12) / 2

• s/2 -12

• s - 6

• s/2 - 6

-12x > 36

• x > -3

• x > 48

• x < -3

- 3( 4 - 2x) = 6

• x = 1

• x = -3 

• x = 3

Choose the expressions that shows a $45 dollar watch discounted 25%.

• 45 - .25 = 44.75

• 45 + .25(45) = 1.25(45)

• 45 - .25(45) = .75(45)

• (x + 7)/2  = 22

• x/2 + 7 = 22

• x + 7/2 = 22
