In one us city the taxi cost is $2 plus $0.90 per mile . if you are traveling from the airport, there is an additional charge of $3.50 for tolls. how far can you travel from the airport by taxi for $41.50?

The answer is 40 miles.

First you have to put it into an equation. When you do this you get .90x+2+3.50=41.50

Now you have to solve using inverse operation. Subtract 3.50 from 41.50 and you get 38.00. Now your equation is .90x+2=38.00

Now you have to subtract 2 form 38.00 and you get 36.00. Now you get .90x=36.00

Then you have to divide 36.00 by .90 and you get 40. Therefore x=40, which means you can travel 40 miles.

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)

step-by-step explanation:

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.
