What is the sum of the rational expressions below? x/x-2 + 7x/x+5 a. 8x/2x+3 b. 8x/x^2+3x-10 c. 8x^2-9x/x^2+3x-10 d. 8x^2-9x/2x+3

answer: 32.68

step-by-step explanation:

x=2

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:
