How Do You Use Addition to Solve an Inequality Word Problem?
Note:
Word problems allow you to see math in action! This tutorial deals with inequalities and money in a bank account. See how to translate a word problem into an inequality, solve the problem, and understand the answer. Take a look!
Background Tutorials
-
Write expressions that record operations with numbers and with letters standing for numbers.
-
What Are Some Words You Can Use To Write Word Problems?
Knowing the mathematical meaning of words allows you to decipher word problems and gives you the power to write your own word problems, too! Take a look at these words and learn their mathematical translations.
-
-
Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations).
-
What is a Variable?
You can't do algebra without working with variables, but variables can be confusing. If you've ever wondered what variables are, then this tutorial is for you!
-
-
Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.
-
How Do You Solve an Inequality Using Addition?
Solving an inequality for a variable? Just perform the order of operations in reverse! Always make sure to follow the rules for solving an inequality!
-
Further Exploration
-
Solve word problems leading to inequalities of the form px + q > r or px + q < 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.
-
How Do You Solve a Word Problem Using a Multi-Step Inequality?
This tutorial provides a great real world application of math. See how to turn a word problem into an inequality. Then solve the inequality by performing the order of operations in reverse. Don't forget that if you multiply or divide by a negative number, you MUST flip the sign of the inequality! That's one of the big differences between solving equalities and solving inequalities.
