What is the explicit rule for the sequence? 10.5, 9, 7.5, 6, 4.5, 3,  an=12.5−1.5n an=11−1.5n an=12+1.5n an=12−1.5n

Step-by-step explanation:

The answer is an=12.5-1.5n

Just in case you all want the rest of the answers to the quiz!!

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:
