Respuesta :
The answer is a because
at start he has 75 the he cuts off a length of rope and gives 56. and the unknown number that he cut off is f.
so 75-f=56
you can also find f, by moving f to the other side and moving the 56 to the left. 75-56=f
so f =19

The above information expressed in a mathematical sentence is 75-f=56.
What is Mathematical modeling?
A real-world problem can be transformed into a mathematical form to provide a better representation and solution. Mathematical modeling is the translation process.
How to solve?
Marcus has a rope that was 75 feet long. And he cut off part of the rope to leave it 56 feet long. Then taking f as the length of rope that is cut off we get
56+f=75
⇒f=75-56
⇒75-f=56
Hence, the given information in the form of a mathematical sentence is 75-f=56.
