Lesson

• 7. EE.4b. Solve word problems leading to
  inequalities of the form px q gt r or px q lt
  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
  bThere are other special symbols that show
  in what way things are not equal.a lt b says
  that a is less than ba gt 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.
