Find the distance between points located at (3,5) and (12, 1). Round to the nearest tenths if necessary. Hint: Plot on a grid.

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:

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

ratio is 2 : 9

the answer is three

13.5 : 3

1. perpendicular

2. parallel

3. perpendicular
