Jesse earns $6 an hour babysitting for his younger brother. His mom gave him $71 last week. This included his babysitting money and his $20 allowance. How many hours did Jesse babysit?

8.5 hours

Step-by-step explanation:

Okay, so he made $71 last week including his $20 allowance. We can take out the allowance 71-20= 51 dollars made from babysitting. But they are asking us to find how many hours he worked.. knowing he gets paid $6 an hour we can divide 51/6 = 8.5 hours babysitting.

Hope this helps :)

8 and a half hours

Step-by-step explanation:

71 minus 20 equals 51 then divide 51 by 6 equalling 8.5 so your answer is about 8 anh a half hours of baby siting

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.
