Which of the following is the product of the rational expression shown below? 5/2x-1 x 5/x

I am assuming that the expression you meant was the following, as it wasn't quite clear - ( ). If that is true, we can simply multiply the numerator and denominators to receive the simplified solution,

Multiplying 5 by 6, you would receive 30. Respectively ( 2x - 1 ) by x should be the following -

And thus, your solution should be 30 / 2x^2 - x. However, we aren't given the options so this answer may be unpredictable.

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:
