The pitch of a roof is found the same way as the slope of a line. what is the pitch of a roof that has a height of 9 ft and a horizontal run of 7? 1/2 2/3 3/2 9/7 in the function y = .08x + 5, y represents the cost of water per gallons and x represents the number of gallons. how much does the cost of water increase for every gallon? x $0.08 $5.00 $5.08

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:
