Every Sunday morning, Opal, Lisa, Talia, and Cora meet for breakfast at the Bagel Shop. They share the bill equally and each pay $2 toward the tip. The expression 1/4x +2 represents
the amount each friend pays, where z is the amount of the bill before the tip.

z is going to be 8 dollars less than the GRAND TOTAL

Step-by-step explanation:

4 multiplied by 2=8.

the number 4 represents the amount of people in the problem.

the number 2 represents the tip amount that each person is paying.

the number 8 represents the total amount of the tip that they all COLLECTIVELY give the waiter.

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.
