Translating Inequalities into Words
Solve and graph Translating Inequalities into Words in Grade 9 algebra. Understand when to flip the inequality sign and how to represent solution sets on a number line.
Key Concepts
Property To write an inequality as a sentence, replace the mathematical symbols for operations (+, , multiplication, division) and comparisons (<, ≥) with their corresponding English words or phrases.
Examples x + 8 6 can be read as "The sum of a number and 8 is greater than 6." 2.5z < 15 can be read as "The product of 2.5 and a number is less than 15." 3x 6 ≤ 30 can be read as "The difference of 3 times a number and 6 is less than or equal to 30.".
Explanation Now you're the storyteller! Turn a math sentence like $x + 8 6$ into a real sentence. You just need to know the 'language' of the symbols, like knowing + means 'the sum of' and means 'is greater than'. It’s a reverse translation challenge!
