Question

a 23 centimeter piece of rope is cut into two pieces. If one piece is z centimeter's long, express the other length as an algebraic expression in z

Answer 1

Answer:

$23 - z$

Step-by-step explanation:

Given

$Length =23cm$

$One\ Piece = z$

Required

Derive an expression for the second piece

Represent the second piece with x,

So, we have:

$x + z = 23cm$

$x + z = 23$

Subtract z from both sides

$x + z - z = 23 -z$

$x = 23 -z$

Hence:

An expression for the second piece is $23 - z$
