If we add the second equation to the first equation, we have a new equation: 7c + 8p = 29.60. Explain why the same (c, p) pair that is a solution to the two original equations is also a solution to this new equation

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:

yes because they have the same amount of green and blur marbles.

step-by-step explanation:

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
