at the afternoon matinee movie, 2 adult tickets and 5 child tickets cost $41, and 4 adult tickets and 2 child tickets cost $42. which two equations can be used to determine the price of each ticket?

let x represent the cost of an adult ticket and y represent the cost of a child ticket.

B

Step-by-step explanation:

Replace the adult ticket with x and child ticket with y.

The mathematical symbol of and is a plus sign, and put an equal sign at 'cost' since it is the total cost.

2x+ 5y= 41

4x + 2y=42

Hence, the answer is B.

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.

answer: i'm not sure
