Marcus has a rope that was 75 feet long. He cut off part of the rope. After that the rope was 56 feet long.

If f= the number of feet marcus cut off the rope, which mathematical sentence expresses the information above

A75-f=56

b)75-f>56

Cf-75>56
Df-75_56

Verified Answer :

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.
