Julie's Yarn Cutting Problem: A Mathematical Equation
In this problem, we are presented with a scenario where Julie needs to cut a specific number of yarn pieces, each with the same length, and an additional piece of yarn with a given length. We will use algebraic equations to represent the situation and find the equation that can be used to solve for the length of each of the equal pieces of yarn.
Julie needs to cut 4 pieces of yarn, each with the same length, and a piece of yarn 7.75 inches long. Let represent the length of each of the equal pieces of yarn that Julie decides to cut. We can represent the total length of the yarn that Julie has as the sum of the lengths of the 4 equal pieces and the additional piece.
Let's denote the total length of the yarn as . We can represent the total length as the sum of the lengths of the 4 equal pieces and the additional piece:
This equation represents the total length of the yarn as a function of the length of each of the equal pieces, .
To solve for , we need to isolate on one side of the equation. We can do this by subtracting 7.75 from both sides of the equation:
Next, we can divide both sides of the equation by 4 to solve for :
This equation represents the length of each of the equal pieces of yarn, , as a function of the total length of the yarn, .
In this problem, we used algebraic equations to represent the situation and find the equation that can be used to solve for the length of each of the equal pieces of yarn. The equation we derived is:
This equation can be used to find the length of each of the equal pieces of yarn, , given the total length of the yarn, .
Suppose Julie has a total of 30 inches of yarn. We can use the equation we derived to find the length of each of the equal pieces of yarn:
Simplifying the equation, we get:
Therefore, each of the equal pieces of yarn should be approximately 5.5625 inches long.
This problem has real-world applications in various fields, such as:
- Textile manufacturing: In textile manufacturing, yarns are cut to specific lengths to create fabrics. This problem can be used to determine the length of each yarn piece.
