Lesson
7. EE.4b. Solve word problems leading to inequalities of the form px + q > r or px + q < r, where p, q, and r are specific
rational numbers. Graph the solution set of the inequality and interpret it in the context of the problem
![Page 6: 7 th Grade Math Week of 11/3/14 Information from : //net.cmsdnet.net/schools/math/sld005.htm](https://reader035.vdocument.in/reader035/viewer/2022062516/56649d6e5503460f94a4ff1f/html5/thumbnails/6.jpg)
Inequalities An inequality says that two values are not equal.
a ≠ b says that a is not equal to b
There are other special symbols that show in what way things are not equal.
a < b says that a is less than ba > b says that a is greater than b(those two are known as strict inequality)
a ≤ b means that a is less than or equal to ba ≥ b means that a is greater than or equal to b.
