Exercise 30 Page 174

We want to write the word sentence as an inequality that it represents. A numberw is greater than - 3Every inequality has an inequality symbol and values or expressions on either side of this symbol. In this exercise, we have the phrase greater than, so we can identify that the inequality symbol should be >. A numberw > - 3 On the left-hand side, we have one key phrase: a number w. These words correspond to arbitrary variable w. On the right-hand side, we have a constant. Putting these sides together, we have a complete inequality. A numberw is greater than - 3 w > - 3
