A mechanic at an auto repair shop completed different repairs on two cars. •The parts for one repair cost $400 and it took the mechanic 3 hours. •The parts for the other repair cost $250 and it took the mechanic 5 hours. •The total bill for each repair was the same amount per hour of labor. The equation below can be used to find c, the cost per hour of labor to repair the cars. 400+3c=250+c What was the cost, in dollars, per hour of labor to repair cars?

Step-by-step explanation:

250 + 5c = 400 + 3c

2c + 250 = 400

2c = 150

c = $75 cost per hour

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x
