What does the symbol '>' mean in an inequality?

Back

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

Front

What does the symbol '<' mean in an inequality?

Back

The symbol '<' means 'less than'. For example, y < 10 means y is less than 10.

Front

What does the symbol '≥' mean in an inequality?

Back

The symbol '≥' means 'greater than or equal to'. For example, z ≥ 3 means z is greater than or equal to 3.

Front

What does the symbol '≤' mean in an inequality?

Back

The symbol '≤' means 'less than or equal to'. For example, a ≤ 7 means a is less than or equal to 7.

How would you write 'You need to score more than 80% to pass' as an inequality?

Back

The inequality would be: s > 80, where s is the score.

Front

How would you write 'The temperature must be less than or equal to 32 degrees to freeze' as an inequality?

Back

The inequality would be: t ≤ 32, where t is the temperature.

Front

If a number is represented by 'x' and it is less than 20, how would you express this?

Back

The inequality would be: x < 20.

Front

If a number 'n' is at least 15, how would you express this in inequality form?

Back

The inequality would be: n ≥ 15.

Front

What inequality represents 'All students must be younger than 18 years old'?

Back

The inequality would be: a < 18, where a is the age of the student.
