Question:

We went to the store last night, and bought three packages of Oreo's. Should the comma be deleted, moved, or kept in this sentence?

The comma should be deleted from the sentence because you are only talking about one item that was bought from the store, not multiple items.

The nucleus of an atom contains protons and neutrons, so the answer is A.

### Subject:Algebra

Question:

What is x if 4x = 8 + 4? Describe the steps you took to find the answer (x)?

Inactive

First, I added 8+4 and 8+4 is 12 (4x=12). The next thing I did was isolate x by dividing both sides by 4 (4x/4=12/4). 4x divided by 4 is x because the 4's cancel each other out. 12 divided by 4 is 3, so x=3.
