The temperature was 23° F at 8 A. M. By 1 P. M. the temperature was 13° F. Which of the following best represents the change in the temperature from 8 A. M. to 1 P. M.?

G: -10 F

Step-by-step explanation: The temparature went down by 10 which means it subtracted 10 so it's -10

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:

f(x)=2/3x-8, which give g(x) the greatest value.
