Complete the parts below.
(a) Solve the given inequality and graph the solution on the number line below.
(b) Choose and complete the statement that best describes the solution.
- To meet the goal, the tank will have less than [] liters of water in it. This will take more than [] minutes.
- To meet the goal, the tank will have less than [] liters of water in it. This will take less than [] minutes.

Answer

(a) Solve the inequality 18x - 11 < 43:

  1. Add 11 to both sides: 18x < 54
  2. Divide both sides by 18: x < 3

The solution is x < 3. Graph this on the number line by shading all values less than 3.

(b) To meet the goal, the tank will have less than 43 liters of water in it. This will take less than 3 minutes.
