Sergei caught 4 stripped fish. each one weighed the same number of pounds. then he caught another fish that weighed 8 pounds. which expression represents the total weight of fish that sergei caught?

4x+8= x because, you already know that the last fish he caught weighed 8 pounds so you do not have to do anything to that number and you know he caught 4 fish so if all four fish weighed the same you would just multiply 4(the number of fish) and x which represents the weight of the fish. So 4 times x equals the total weight of the four fish plus the 8 pounds of the last fish should get you the total weight of all the fish he caught.

Fine until slavery ya ya haha
