The mass of the earth is 5.97 ✕ 1024 kg, and the mass of the moon is 7.35 ✕ 1022 kg. the distance of separation, measured between their centers, is 3.84 ✕ 108 m. locate the center of mass of the earth-moon system as measured from the center of the earth.

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:
