One Step Equations and Inequalities

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions using symbols like <, >, ≤, or ≥.

Front

What does the symbol < mean?

Back

The symbol < means 'less than'. For example, x < 3 means x is less than 3.

Front

How do you solve the equation ½x = 4?

Back

To solve ½x = 4, multiply both sides by 2. So, x = 8.

Front

What is the solution to the equation z/8 = 16?

Back

To solve z/8 = 16, multiply both sides by 8. So, z = 128.

Front

What does the inequality 15 < x - 3 mean?

Back

It means that x - 3 is greater than 15, or x > 18.

Front

How do you solve the equation k ÷ 8 = 4?

Back

To solve k ÷ 8 = 4, multiply both sides by 8. So, k = 32.

Front

What is the solution set for the inequality k < 3?

Back

The solution set includes all numbers less than 3.

Front

What does the symbol > mean?

Back

The symbol > means 'greater than'. For example, x > 5 means x is greater than 5.

Front

How do you graph the inequality k < 3?

Back

To graph k < 3, draw a number line, place an open circle at 3, and shade to the left.

Front

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal, while an inequality shows that one expression is greater or less than another.
