Let's kick it up a notch. Use what you know about distributing and solving two-step inequalities when solving for n.

6(n + 2) < -72

• n < -14

• n < 35/3

• n < -10

• ∞

Let's kick it up another notch. Use what you know about distributing, combining like terms and solving two-step inequalities when solving for x.

7(x + 3) - 5x < 13

• x>-4

• x < 17

• x<-4

• x > -17

Ok. Try this last one.Remember...use what you know about distributing, combining like terms and solving two-step inequalities when solving for x.

-3 − 6(4x + 6) > -111

• x > 3

• x < 3

• x < -3

• x > -3

• f < 0.5

• f > 0.5

• f < 1.2

• f > 1.2

Distribute and solve:

-2(x+2) < 14

• x < - 5

• x > -5

• x < -9

• x > -9

Solve for k in the following inequality and choose the best answer to match the graph: 2k - 9 ≤ -19

• The graph would have a closed circle shaded left at -5.

• The graph would have a closed circle shaded left of 5.

• The graph would have an open circle shaded left of -5.

• The graph would have an open circle shaded left of 5.
