What are examples of inequalities?
The expression 5x − 4 > 2x + 3 looks like an equation but with the equals sign replaced by an arrowhead. It is an example of an inequality. This denotes that the part on the left, 5x − 4, is greater than the part on the right, 2x + 3.
Which is the best definition of an inequality?
Definition of inequality
1 : the quality of being unequal or uneven: such as. a : social disparity. b : disparity of distribution or opportunity. c : lack of evenness. d : the condition of being variable : changeableness.
How do you identify an inequality?
These inequality symbols are: less than (<), greater than (>), less than or equal (≤), greater than or equal (≥) and the not equal symbol (≠). Inequalities are used to compare numbers and determine the range or ranges of values that satisfy the conditions of a given variable.

What does and mean in inequalities?
A compound inequality is a sentence with two inequality statements joined either by the word “or” or by the word “and.” “And” indicates that both statements of the compound sentence are true at the same time. It is the overlap or intersection of the solution sets for the individual statements.
What are the rules of inequalities?
Inequality Meaning
- p ≠ q means that p is not equal to q.
- p < q means that p is less than q.
- p > q means that p is greater than q.
- p ≤ q means that p is less than or equal to q.
- p ≥ q means that p is greater than or equal to q.
What are the 4 steps to solving inequalities?
To solve an inequality, we can:
- Add the same number to both sides.
- Subtract the same number from both sides.
- Multiply both sides by the same positive number.
- Divide both sides by the same positive number.
- Multiply both sides by the same negative number and reverse the sign.

How do you know if an equation is an inequality?
Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are deemed equal which is shown by the symbol =. Where as in an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
