Missy uses 1 hexagonal, 2 rectangular, and 5 triangular pieces of fabric to make 1 bug design for a quilt. If she uses 80 pieces in all to make bug designs, how many of each shape does she use? Enter the correct answer.

10 Hexagonal pieces, 20 Rectangular pieces and 50 Triangular pieces.

Step-by-step explanation:

First let's check how many pieces Missy uses to make one bug design:

1 hexagonal + 2 rectangular + 5 triangular = 8 total pieces.

Is the uses 80 pieces in total, she made a total of 80/8 = 10 bug designs

So now we can calculate how many pieces of each shape she uses just multiplying the amount of bug designs (10) by the number of pieces of each shape:

Hexagonal pieces: 1 * 10 = 10 pieces

Rectangular pieces: 2 * 10 = 20 pieces

Triangular pieces: 5 * 10 = 50 pieces
