If ABC ~ XYZ fi d XY. A 20. B 21. C 24. D not possible

Choice D: not possible

Step-by-step explanation:

The reason why it's not possible is that when you try to make an equation it never comes out correct. You could also try plugging in the numbers then figure it out that way. It's not possible either way you do it.

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:
