Joey and Emily's teacher gave them each a triangle divided into three parts-A, B, and C- figure that will prove that the sum of the interior angles of a triangle is always equal to 18 Joey's and Emily's figures are shown below. Joey's Figure Emily's Figure

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:

my answer is$ 12

step-by-step explanation:

because 15 -2=12
