Answer:
The answer to your question is:
first piece 44/3
second piece 35/3
third piece 5/3
Step-by-step explanation:
First we define the variable, it will be "x", and will be for the second piece.
Second piece = x
First piece = x + 3 (from the problem)
Third piece = x - 10 (from the problem)
We sum all
x + 3 + x + x -10 = 28
3x - 7 = 28 simplify like terms
3x = 28 + 7
3x = 35
Second piece x = 35/3
First piece = x + 3 = 35/3 +3 = (35 + 9)/3 = 44/3
Third piece = 35/3 - 10 = (35-10)/3 = 5/3
