Video: Writing Linear Inequalities

Video Transcript

Write an expression for 𝑐 which means it is less than or equal to three.

There are four types of inequality signs: greater than, less than, greater than or equal to, or less than or equal to. In this question, we’re writing an expression for 𝑐 in terms of the number three. This means that 𝑐 could be greater than three. Our second inequality sign shows that 𝑐 is less than three. The third option shows that 𝑐 is greater than or equal to three. And our fourth and final option is that 𝑐 is less than or equal to three.

In this question, we’re asked to write an expression where 𝑐 is less than or equal to three. This means that the bottom option is correct.
