<span>Given: 2 vans
let van 1 seats = x
</span><span>let van 2 seats = y = x + 6</span><span>

 Total # trips larger = 1 trip
 total # trips small = 2 trips
  max # people = 57 each
 
2x + y = 57
 2x + (x + 6) = 57
  3x = 51
 x = 51/3 = 17 people
 
y = x + 6 = 17 + 6 = 23 people
 
check: 2x + y = 57 2(17) + 23 = 34 + 23 = 57

Thus, the small van can carry 17 passengers the large van can carry 23 passengers</span>

Tems11 [23]

Answer:

1521.16402

Step-by-step explanation:

use fraction- division format\frac{x}{y}

\frac{5750}{3.78}

Multiply the numerator and denominator by 100

\frac{575000}{378}

Reduce by 2

\frac{287500}{189}

Now do long division

          1521. 164022

189|287500

   -  189

        985

     -  945

                          40

                         -  0

                           400

                         - 378

There are five times as many cars as trucks on the road. Which fraction represents the number of vehicles that are trucks?
jonny [76]
Well, the ratio of cars to trucks is 5:1, so for every 1 truck, there are 5 cars, the sum would be 6. So that's the denominator, and then the numerator would be 1, since there's only 1 truck out of every 6 vehicles.
