Monday: Bell Work After paying 8 dollars for the pie, Nancy has 75 dollars left. How much money did she have before buying the pie ? There were 31 bales of hay in the barn. Benny stacked more bales in the barn today. There are now 53 bales of hay in the barn. How many bales did he store in the barn ? 1) write the correct equations for both problems 2) solve

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

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 b a > 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 b a ≥ b means that a is greater than or equal to b.

Inequalities Symbol Word Circle > greater than ○ < less than ○ ≥ greater than or equal to ● ≤ less than or equal to ●
