3. Juan caught a fish that weighed 7.5 pounds. Orlando caught 3 fish that
each weighed the same. All 4 fish
together weighed 32.25 pounds.
What is the weight, x, of Orlando's
fish?

24.75

Explanation:

The first thing you need to do is subtract 32.25 which is the total minus 7.5 which is Juan's total then you will get the answer of 24.75.       If you want to find out how much each one of Orlando's fish weighed all you have to do is divide 24.75 by 3 and you get 8.25.

the answer is "a.) well–developed vascular system."
