The equation that represents how many items are on each list is option B) x + (x-9) = 33.
<u>Step-by-step explanation</u>:
There are two different lists of grocery.
The number of items in the 1st grocery list = x
The number of items in the 2nd grocery list differs by 9 from the number of items in the 1st grocery list.
Therefore, the number of items in the 2nd grocery list = (x-9)
The total number of items for both lists = 33.
<u>The equation can be formed as :</u>
number of items in the 1st list + number of items in the 2nd list = total number of items.
⇒ x + (x-9) = 33
The equation that represents how many items are on each list is x + (x-9) = 33.
