What is an inequality for The Washington Monument is 555 feet tall.It is 75 feet shorter than the Gateway to the West Arch

Answer 1

155 - 75 = Gateway

80 = Gateway

This is not an inequality. An in equality would require the following sort of wording: The Gateway is less than the Washington Monument at 55 ft by 75 feet.

The words "less than" or "greater than" are required for an inequality. Or, "less than or equal to" or "greater than or equal to".
