Exercise 13 Page 149

The phrase more than divides the sentence into what should be on the left-hand side and what should be on the right-hand side of the inequality.

w + 2.3 > 18

Practice makes perfect

We are given a verbal expression and we want to write an inequality that it represents.

A number w added to 2.3 is more than 18.

Every inequality has an inequality symbol and values or expressions on either side of this symbol. In this exercise, we have the phrase more than, so we can identify that the inequality symbol should be >.

A numberw added to 2.3 > 18 On the left-hand side, we have one key phrase: added to. These words tell us the operations that will be used in our inequality. Added to indicates addition. A numberw added to 2.3 w + 2.3 On the right-hand side, we have a constant. Putting these sides together, we have a complete inequality. A numberw added to 2.3 is more than 18. w + 2.3 > 18
