Amy is building a house. The basement floor is at -15 feet. The roof of the house is above the ground 25 feet. Write an inequality to compare the heights & then explain the meaning of the inequality.

-15 < 25

To write an inequality comparing the heights of the basement floor and the roof of the house, we can use the greater than symbol (>) or the less than symbol (<) to represent the comparison.

Since the basement floor is at -15 feet and the roof of the house is 25 feet above the ground, we can write the inequality as:

-15 < x < 25

In this inequality, "x" represents the height above the ground level. The less than symbol (<) indicates that the height must be greater than -15 feet (the basement floor height), and the greater than symbol (>) indicates that the height must be less than 25 feet (the height of the roof).

So, the inequality -15 < x < 25 means that the height of the house above the ground level must be greater than -15 feet and less than 25 feet.
