Reminder: variables are on both sides

yarga [219]

Start by multiplying both sides of the equation by 7 (the common denominator).

$7 \left(\frac{6z}{7} -27 \right)=7\left(\frac{21-4z}{7} \right) \\ 6z-189=21-4z$

Add 4z to both sides.

$10z-189=21$

Add 189.

$10z=210 \\ z=21$

a taxi company charges passengers $1.75for a ride, no matter how long the ride is and an additional .40 for each mile traveled.

DerKrebs [107]

The relationship between the miles and the total cost is, for every 1 mile at the cost of $.40 you will have to pay an initial fee of $1.75.

The charge for a one-mile drive is $2.15 (C=.40*1+1.75)

The charge for a 2.7 mile ride will be $2.83 (C=.40*2.7+1.75)
