How many ways can three items be selected from a group of six items?
use the letters a, b, c, d, e, and f to identify the items, and list each of the different combinations of three items. (enter your answers as a comma-separated list. enter three unspaced capital letters for each combination.)

right

step-by-step explanation:

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:

understand that i don't know the answers

will someone answer his question

3 is greater then both of those numbers
