Answer 1

The weight of the fourth horse must be less than 1420 pounds for it to be on the trailer.

Inequality

Inequality is an expression used to show the non equal comparison of two or more numbers and variables.

Let x represent the weight of the fourth horse.

From the question:

x + 890 + 1250 + 940 ≤ 4500

x + 3080 ≤ 4500

x ≤ 1420

The weight of the fourth horse must be less than 1420 pounds for it to be on the trailer.
