6th 4-6 Understand and Write Inequalities

Front

What is an inequality?

Back

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

Front

What does the symbol < mean in an inequality?

Back

The symbol < means 'less than'. For example, s < 40 means s is less than 40.

Front

What does the symbol > mean in an inequality?

Back

The symbol > means 'greater than'. For example, w > 12 means w is greater than 12.

Front

What does the symbol ≤ mean in an inequality?

Back

The symbol ≤ means 'less than or equal to'. For example, s ≤ 40 means s is less than or equal to 40.

Front

What does the symbol ≥ mean in an inequality?

Back

The symbol ≥ means 'greater than or equal to'. For example, m ≥ 45 means m is greater than or equal to 45.

Front

How do you write 'the height of the shrub is 36.5 inches' as an equation?

Back

You write it as s = 36.5.

Front

If s < 40, what can you say about the value of s?

Back

s can be any value that is less than 40.

Front

If w ≤ 12, what does this imply about w?

Back

w can be any value that is less than or equal to 12.

Front

How would you express 'the temperature is at least 30 degrees' using an inequality?

Back

You would express it as T ≥ 30.

Front

What is the solution set for the inequality s < 40?

Back

The solution set includes all real numbers less than 40.
