There are three consecutive numbers such that 3 times the greatest decreased by five times the middle number is-33

Step-by-step explanation:

Let (n-1), n, and (n+1) be the consecutive numbers.

3(n+1) - 5n = = -33

-2n + 3 = -33

-2n = -36

n = 18

The numbers are 17, 18, 19

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:
