When modeling word problems as mathematical equations, which of the following is a synonym for the division operation? a. difference b. decreased c. per d. combined

First, we can see the wrong options.

The option A, difference implies a subtraction, so the difference between A and B is: A - B.

The option B, Decreased, also implies a subtraction. Used in the form " the number A decreased by the number B" this is A - B

The option D, combination, implies a multiplication, so the combination of A and B is A*B

The answer is C, per.

Per is used in the next way, when you say that some object has a speed of 100 km per hour, this is written as 100km/h

So if i say " you can get 10 pens per 5 dollars" then you got that a pen costs for a dollar you can get 10/5 =  2 pens.

where are the choices?

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
