Inequalities Writing

Writing Inequalities are slightly different from expressions and equations in that they have an inequality. For example… 3 x – 4 Expression 3 x – 4 = 8 Equation 3 x – 4 > 8 Inequality There are 4 inequality signs, each with their own vocabulary: < is less than, is less than > is more than, is greater than ≤ at most, is less than or equal to, is small than or equal to, no more than ≥ at least, is more than or equal to, is greater than or equal to, no less than

Writing Inequalities When writing inequalities, it is important that you interpret what you read…this is the idea of circling and converting your data. For example… Chris wants to order DVDs over the internet. Each DVD costs $15 and shipping for the entire order is $9. Christ has no more than $100 to spend. Write an equality that shows how many DVDs Chris can buy. 15 d + 9 ≤ 100

Two less than the quotient of a number and three is no more than 9. Double the sum of a number and one is no less than eight. 5. Triple the difference of three and a 10. One more than a third of a number is at least twenty-eight. The sum of a number and four divided by three is at most one. 11. The difference of a number and six times four is no more than number is at most twelve. 6. Triple the difference of a number and four is at least twenty-one. nineteen. 4. The product of six and the sum of three and a number is less than fourteen. 3. Three-fourths of a number plus eight. 12. Five less than two-fifths a number is greater than or equal to thirtyfive.
