Daniel wanted to make note cards by cuttin pieces of paper in half. before starting he got 3 more pieces to use. when he was done he had 20 half pieces of paper. with how many pieces did he start​

Answer 1

7

Explanation:

If he ended up with 20 half pieces, then he cut 10 pieces in half since 20/2 = 10.

Before starting to cut he got 3 more pieces, so he had 3 fewer than 10.

Answer: He started with 7 pieces of paper.

Check:

Start with 7 pieces of paper.

Add 3 pieces of paper to end up with 10 pieces of paper.

Cut the 10 pieces of paper to end up with 20 half pieces.

He did end up with 20 half pieces, so he started with 7.
