The cruise ship traveled n miles per hour for t hours and was 30 miles short of the harbor when the horn was sounded. if the captain tried again, how long would it take to reach the harbor if she increased the rate of travel by 15 mph?

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:

umm. i dont know

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.

27 +27 or 27times 2=54

the diffrence is 0
