Writing Inequalities

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.' It indicates that a value can be either less than or equal to another value.

Front

What does the symbol ≥ mean?

Back

The symbol ≥ means 'greater than or equal to.' It indicates that a value can be either greater than or equal to another value.

Front

If s ≤ 35, which values are solutions?

Back

Any value less than or equal to 35, such as 25, 30, or 35.

Front

Which value is NOT a solution for s ≤ 35?

Back

42 is NOT a solution because it is greater than 35.

Front

How do you express 'no more than 18 students' in inequality form?

Back

s ≤ 18.

Front

What does the inequality r ≥ -6 represent?

Back

It represents all values of r that are greater than or equal to -6.

Front

How would you express 'fewer than 150 children' in inequality form?

Back

c < 150.

Front

What is the difference between < and ≤?

Back

< means 'less than' (not including the number), while ≤ means 'less than or equal to' (including the number).

Front

What does the graph of an inequality show?

Back

The graph of an inequality shows all the possible solutions that satisfy the inequality.
