Answer 1

Definition

Inequality is the relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than', or < ‘less than'.

1.

a. h > 50

Answer: greater than

b. h <= 20

less than or equal to

c. 30 >= h

greater than or equal to

2.

Is 25 a solution to any of the inequalities?

Yes. 25 is a solution to the inequality 30 >= h

We can rewrite this inequality as:

`h\text{ }\leq\text{ 30}`

The inequality means that h can take values that are less than 30 or equal to 30

3. Is 40 a solution to any of the inequalities?

No. 40 is not a solution to any of the inequalities

4. Is 30 a solution to any of the inequalities?

Yes. 30 is a solution to the inequality 30 >= h
