Alright well for (A) you will round $5280 to $5300. Then you multiply $5300 by 28.
For (B) you just round up. So again $5280 rounds up to $5300.
Place value can be used to subtract 4.23 and 2.75 because, in order to subtract, you must line up the whole numbers together, the tenths place together, and the hundredths place together.
Lining them up: Whole= W Tenths place= T Hundredths place= H
W T H
4 . 2 3
- 2 . 7 5

1 . 4 8
We are given the following equation and want to find which value of x will make it true:

Subtract 3 from both sides

Divide both sides by -6

Thus, the value that will make 3-6x=21 is x=-3. Let me know if you need any clarifications, thanks!
