<em>Complete Question:</em>
<em>Henry places x marbles into an empty bucket. Each marble has the same weight. The weight, in ounces, of the bucket and marbles can be calculated using the expression shown: 3x + 8
</em>
<em>What does the term 8 represent in this expression?
</em>
Answer:
The weight of the bucket

What does 8 represent?
The given expression illustrates the weight of the whole system i.e. bucket and marbles
i.e.
![Weight = Weight\ of\ x\ marble + Weight\ of\ Bucket](https://tex.z-dn.net/?f=Weight%20%3D%20Weight%5C%20of%5C%20x%5C%20marble%20%2B%20Weight%5C%20of%5C%20Bucket)
Since there are x marbles, by comparison:
![Weight\ of\ x\ marble = 3x](https://tex.z-dn.net/?f=Weight%5C%20of%5C%20x%5C%20marble%20%3D%203x)
![Weight\ of\ bucket = 8](https://tex.z-dn.net/?f=Weight%5C%20of%5C%20bucket%20%3D%208)
<em>Hence, 8 represents the weight of the bucket</em>
