1.braden finished his math test 14 minutes before ariana did
if it took ariana 57 minutes and they both started the test at the same time how long did it take bradden?

2. sarah and eva took a road trip
sarah drobe two-fifths of the miles
if she drove 128 miles how many total miles did they drive?

direction: for each problem define a variable and set up an equation, then solve
and you

Question 1

You would have to use the equation of 57-14=x or x+14=57

Either way you would have to use 57 minus 14 equals x.

57-14= 43

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.

the answer

b. they are parallel and will never intersect.
