Front

What is an inequality?

Back

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

Front

What does the symbol '≤' mean?

Back

The symbol '≤' means 'less than or equal to'.

Front

What does the symbol '≥' mean?

Back

Front

How do you represent 'no more than 18 students' in an inequality?

Back

s ≤ 18

Front

How do you represent 'fewer than 150 children' in an inequality?

Back

c < 150

Front

What does it mean to solve an inequality?

Back

To solve an inequality means to find all values of the variable that make the inequality true.

Front

What happens to the inequality sign when you multiply or divide by a negative number?

Back

The inequality sign flips (changes direction).

Front

Solve the inequality: 5x + 3 < 18.

Back

x < 3.

Front

What is the first step in solving the inequality 22 < 6c + 4?

Back

Subtract 4 from both sides: 18 < 6c.

Front

What is the solution to the inequality 22.50 + x > 32?

Back

x > 9.50.
