Translating Sentences into Inequalities
Translate verbal sentences into algebraic inequalities in Grade 9 Algebra. Recognize key phrases like 'at least,' 'no more than,' and 'exceeds' to choose the correct symbol.
Key Concepts
Property To translate a sentence into an inequality, identify the key operations (sum, product, quotient) and inequality phrases ('is less than', 'is at least') to construct the correct mathematical expression.
Examples "The quotient of a number and 2 is less than or equal to 6" translates to $\frac{n}{2} \leq 6$. "The sum of the product of 20 and a number and 75 is at least 195" translates to $20x + 75 \geq 195$. "The difference of a number and 2.8 does not equal 8.2" translates to $g 2.8 \neq 8.2$.
Explanation This is like being a codebreaker! You're translating English into the language of math. Look for clue words like 'quotient' for division or 'at least' for $≥$. Each word gives you a piece of the puzzle, letting you build the final inequality that solves the mystery.
