Answer:
<h2>The length of the pieces is 3 inch, 6 inch and 13 inch.</h2>Step-by-step explanation:
Let, the length of the first piece is x inch.
Hence, the length of the second piece is 2x.
It is given that, the length of the third piece is one inch more than four times of the first piece. Hence, the length of the third piece is 4x + 1 inch.
The total length of the steel is 22 inch.
Hence, x + 2x + 4x + 1 = 22
or, 7x = 21
or, x = 3.
The length of the second piece is 6 inch.
The length of the third piece is 13 inch.
Answer:
The value of x is reciprocal of the difference of a and b.
Step-by-step explanation:
We are given the equation,
On simplifying, we get,
i.e.
i.e.
i.e.
So, we get,
The value of x is .
That is, the value of x is reciprocal of the difference of a and b.
