Lesson 4: How to Write Inequalities from Verbal Expressions

Content Standards and Objectives M.6. EE. 8 (CCSS.6.EE.B.8) Write an inequality of the form x > c or x c or x < c have infinitely many solutions. Represent solutions of such inequalities on number line diagrams.

Given: The Maximum weight for bumper cars is 200 pounds

Step 1: Choose a Variable for the weight. Let w = the possible weights

Step 2 : Determine the Range of Possible Values Range: All numbers less than or equal to 200

Step Three: Determine the Symbol to Show Inequality The weight must be less than or equal 200. We should use the symbol ≤

Step 4: Combine the Numbers and Variables With the Inequality Symbol w ≤ 200

Now, Try An Example on Your Own Given: All snacks are greater than or equal to $4.00

All Snacks are Greater Than or Equal to $4.00 Let s = the cost of snacks The range is : $4.00 and up The symbol is ≥. The inequality is s ≥ $4.00
