Final answer:
The question suggests a mathematical problem with a system of equations involving lengths of rope, but it is incomplete. The conversion of feet to inches is straightforward: 10 feet is 120 inches. A full problem statement is necessary to provide a specific solution.
Step-by-step explanation:
The question provided seems to be related to a mathematical problem involving a system of equations, specifically dealing with the lengths of rope; This is a typical question you might encounter in an algebra class. Unfortunately, the question is incomplete, as it does not provide the actual system of equations or additional details needed to solve for the specified lengths of rope. Therefore, a general approach to this kind of problem would involve setting up two equations to represent the relationships outlined in the problem (once the full problem is presented), and then using algebraic methods to find the values of the variables representing the lengths of rope.
For the rope conversion part, to convert feet to inches, we use the fact that one foot equals twelve inches. So, if John has a rope that is 10 feet long, to find the length in inches, we multiply 10 feet by 12 inches per foot, which results in 120 inches.
The reference to a problem involving nylon rope and meters of fishing line indicates that you might also need to use unit conversion and proportions within the context of the question. To successfully answer the original question, the full problem statement including the system of equations or a description of the scenario involving the rope lengths would be required.
