A
B
C
D??

Answer:
B.)
Step-by-step explanation:
In the equation 3x+8
3 would be the number of marbles, since x is the weight of the marble, and 8 would be the weight of the empty bucket.
The equation is finding the weight of the bucket, therefore we need to add the weight of the bucket (8) and the weight of the marbles.
Answer:
I think it might be C
Step-by-step explanation:
I think it might be it because it said that the equation will tell you the weight of the bucket and the marble and if that were the weight then there would be your answer. So I think that it can't be A or B. And D is kind of the same thing as the others and it never said how many marbles are in the empty bucket so I think that C might be you answer.
