Suppose you are fencing a retangular puppy kennel agaisnt your house. you have 42 feet of fence to use for the other three sides of the kennel. the side of the kennel across from the side of the house is 3 feet longer than the two shorter sides. find the length of the longest side of the kennel.

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:

(x, y)→(x − 8, y − 7)

step-by-step explanation:

enjoy!
