Exercise 16 Page 149

The phrase no less 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.

- 5/9≥ 5* k

Practice makes perfect
We are given a verbal expression and we want to write an inequality that it represents. - 59is no less than 5times a numberk Every inequality has an inequality symbol and values or expressions on either side of this symbol. In this exercise, we have the phrase no less than, so we can identify that the inequality symbol should be ≥.

- 59 ≥ 5times a numberk On the right-hand side, we have one key phrase: times. This words tell us the operation that will be used in our inequality. Times indicates the multiplication. 5 times a numberk 5 * k On the left-hand side, we have a constant. Putting these sides together, we have a complete inequality. - 59 is no less than 5 times a numberk. - 5/9 ≥ 5 * k
