The winner of a weight-lifting competition bench-pressed 400 pounds. all other competitors bench-pressed at least 23 pounds less. write an inequality that represents the weights x (in pounds) that the other competitors bench-pressed.

Step-by-step explanation:

Let

x -----> the weights (in pounds) that the other competitors bench-pressed

Since the other competitors bench-pressed at least 23 pounds less than 400 pounds

That means ---> The maximum weight that other competitors could bench press was (400-23)=377 pounds

therefore

The inequality for this problem should be

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

so, converting firstly the mixed fractions to improper fractions and then "adding".
