13. Rectangle QUAD has coordinates Q(0, 0), 4(0, 3), A6, 3), and D(6,0).
Q'U'A'D' is the image of QUAD after a dilation with center (0,0) and
a scale factor of 6. What are the coordinates of point D'?

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:

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
