Mark, jessica, and nate each downloaded music from the same website. mark downloaded 10 songs in total consisting of pop, rock, and hip hop. jessica downloaded five times as many pop songs, twice as many rock songs, and three times as many hip hop songs as mark. she downloaded 28 songs total. nate downloaded 20 songs total with three times as many pop songs, three times as many rock songs, and the same number of hip hop songs as mark. which system of equations represents their music choices?

x + y + z = 10
5x + 2y + 3z = 28
3x + 3y + z = 20

x + y + z = 10
2x + 5y + 3z = 28
3x + 3y + z = 20

x + y + z = 10
5x + 2y + 3z = 28
3x + 3y + 3z = 20

x + y + z = 10
2x + 3y + 5z = 28
x + 3y + 3z = 20

x + y + z = 10

5x + 2y + 3z = 28

3x + 3y + z = 20

Step-by-step explanation:

(I think)

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.

hope this is what you were asking for!
