Solve each of the following equations or inequalities and graph the solution on a number line. Homework Help ✎

  1. Make the inequality an equation and use inverse operations to undo the equation and solve for the variable.

    Make a number line and use a dot to represent the solution of the equation. Then, test numbers on both sides of the solution to see which side makes the inequality true and graph the rest of the solution.

  2. Try undoing the equation using inverse operations.

    y = 64.72 ÷ 8
    y = 8.09

    Now use a dot to represent the solution on a number line.

  3. See part (a).
