Aphotograph measuring 2 inches by 3.6 inches is enlarged to increase the original 2-inch dimension to 5 inches. when this is done, how long does the original 3.6-inch dimension become?

9 inches

Step-by-step explanation:

2 x 2.5 = 5

3.6 x 2.5 = 9

the answer is 8

step-by-step explanation:

3.14 x 8x8

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:
