Exercise 6 Page 58

Start forming the inequality by first determining the correct inequality symbol.

n+7≤ 9

Practice makes perfect

To write a verbal inequality in algebraic terms, we will start by identifying the inequality symbol we need to use and placing it in the center of our statement. In this case we have less than or equal to, which is represented by the symbol ≤. ... ≤ ...

On the left-hand side of the inequality we have a number n plus 7, which we will express as a sum. n+7≤... On the right-hand side of the inequality we have 9. We can now form our final answer. a numbern plus 7is less than or equal to9 n + 7≤9
