15. Table What does this word mean to you? This word actually means….. an arrangement of words, numbers, or signs, in columns, to show a set of facts or relations.. Examples… Explain how you would use this word in math.

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 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 SymbolWord >greater than <less than ≥greater than or equal to (The line underneath the Greater Than sign indicates also Equal To.) ≤less than or equal to (The line underneath the Less Than sign indicates also Equal To.)

Graphing Inequality Symbols : Greater Than (The open circle indicates that this is NOT EQUAL TOO the number that is graphed.) Greater Than or Equal To (The closed circle indicates that this is EQUAL TO the number that is graphed.)

Less Than (The open circle indicates that this is NOT EQUAL TO the number that is graphed.) Less Than or Equal To (The closed circle indicates that this is EQUAL TO the number that is graphed.)

Exit / Closure On a piece of paper write the following: What was today’s objective and was it met?

Wednesday: Bell Work Melanie had 38 peaches left at her roadside fruit stand. She went to the orchard and picked more peaches to stock up the stand. There are now 92 peaches at the stand, how many did she pick ? 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

Exit / Closure Journal Entry How the answers to inqualities different than the answers to equations?

Thursday: Bell Work Write an inequality to model the situations. 1) Thomas earned $44 or more. 2) Suppose you had d dollars in your bank account. You spent $22 but have at least $28 left. How much money did you have initially? Write and solve an inequality that represents this situation.
