His cousin is 15.

Subtract and then divide.

Step-by-step explanation:

So, Santosh (49) is 4 years older than the triple of the age of his cousin (c)... we then get this equation system:

49 = 4 + 3c

We just have to resolve this simple system to find the age of the cousin.

We first subtract 4 on each side:

45 = 3c

Then we divide each side by 3:

15 = c

His cousin is 15 years old.

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.

so what is the question
