Show how to use the greatest common factor of 84 and 72 to rewrite 84m - 72n as a product of two factors

The simplified expression is: 12(7m - 6n)

Step-by-step explanation:

Greatest common factor between 84 and 72

We keep dividing 84 and 72, while they can be divided by the same factor. So

84 - 72| 2

42 - 36|2

21 - 18|3

7 - 6

So the greatest common factor is 2*2*3 = 12.

Rewrite 84m - 72n as a product of two factors

Evidencing 12

step-by-step explanation:

i think you should think about the question and not look online.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
