What are the like terms in the expression below?

3x+8+3y+8x

Correct

C) 3x and 8x

Step-by-step explanation:

At first I thought the correct answer was D.

You may have thought that too, but that is not the correct answer.

You see 3x and 8x are both like terms because they both have x

the other 3 does not have an x it has y

Step-by-step explanation:

The like terms would be 3x and 8x

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:
