Question 881201
A + B + C = 15
A = B + 3.57
C = B + 2.97
Substitute the known values of A and C in the 2nd and 3rd equations into the first.
(B+3.57) + B + (B+2.97) = 15
Add
3B + 6.54 = 15
Subtract 6.54 from each side
3B = 8.46
Divide each side by 3
B = 2.82
.
If the length of the second piece is 2.82, then A is 2.82+3.57, or 6.39
C is 2.82+2.97, or 5.79
The lengths are 6.39, 2.82, and 5.79
