Answer:
Length of first piece = 5 inches
Length of second piece = 10 inches
Length of third piece = 26 inches
Step-by-step explanation:
Given that:
Length of piece of steel = 41 inch
Let,
x be the length of first piece
y be the length of second piece
z be the length of third piece
According to given statement;
x+y+z = 41 Eqn 1
y = 2x Eqn 2
z = 5x+1 Eqn 3
Putting value of y and z from Eqn 2 and 3 in Eqn 1
[tex]x+2x+5x+1=41\\8x = 41-1 \\8x = 40[/tex]
Dividing both sides by 8
[tex]\frac{8x}{8}=\frac{40}{8}\\x=5[/tex]
Putting x=5 in Eqn 2 and 3
y = 2(5) = 10
z = 5(5) + 1 = 25+1 = 26
Hence,
Length of first piece = 5 inches
Length of second piece = 10 inches
Length of third piece = 26 inches
