Suppose you write a sum of numbers as a product of their gcf and another sum. what is the gcf of the numbers in the other sum? explain.

1.

Step-by-step explanation:

We are asked to determine the GCF of the numbers in the other sum.

Since we have already factored out the GCF from initial or starting numbers, then the sum of other numbers will share no common factor other than 1.

For example let us take two numbers 15 and 25.

Sum of 15 and 25:

We know the greatest common factor of 15 and 25 is 5.

Factor out 5 from the sum:

Now, we can see that the greatest common factor of 3 and 5 is 1.

Therefore, the GCF of the numbers in the other sum would be 1.

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:
