Question

During one month, a rental agency rented a total of 155 cars, trucks, and vans. Nine times as many cars were rented as vans, and three times as many vans were rented as trucks. Let x represent cars, let y represent vans and let z represent trucks. Write a system of three equations that represent the number of each vehicle rented

Answer 1

Answer:

The system of three equations is equal to

$x+y+z=155$

$y=9x$

$z=3y$

Step-by-step explanation:

Let

x ----> the number of cars rented during one month

y ----> the number of vans rented during one month

z ----> the number of trucks rented during one month

we know that

$x+y+z=155$ ----> equation A

$y=9x$ ---> equation B

$z=3y$ ----> equation C
