1. The problem is to express inequalities in sentence form, specifically how to state that one quantity is greater than or less than another. 2. The key formulas or symbols involved are: - Greater than: $a > b$ means "a is greater than b." - Less than: $a < b$ means "a is less than b." 3. Important rules: - Use "greater than" when the first value is larger than the second. - Use "less than" when the first value is smaller than the second. - For "greater than or equal to" ($a \geq b$), say "a is greater than or equal to b." - For "less than or equal to" ($a \leq b$), say "a is less than or equal to b." 4. Example: - If $x > 5$, say "x is greater than 5." - If $y < 10$, say "y is less than 10." 5. In summary, to establish inequalities in sentence form, identify the inequality symbol and translate it directly into words as shown above.
