mylen [45]

3m {}^{2}  +  {2p}^{2}  - 15
m = 3
p = 10

3 \times 3 {}^{2}  + 2 \times  {10}^{2}  - 15 =
3 \times 9 + 2 \times 100 - 15 =
27 + 200 - 15 =

A roller coaster has four cars each with the same number of seats. these are 21 passengers seated in the roller coaster, but 3 s
belka [17]

Given:

Number of passengers seated in the roller coaster = 21

Empty seats = 3

Number of cars in roller coaster = 4 (each with the same number of seats)

To find:

An equation that can be used to determine the number of seats in each car.

Solution:

Let s be the number of seats in each car.

Total number of seats in 4 cars = 4s

Using the given information,

Total number of seats = Occupied seated + Empty seats

                                   = 21 + 3

                                   = 24

Now, the required equation is

4s=24

Therefore, the required equation is 4s=24.

Divide both sides by 4.

s=\dfrac{24}{4}

s=6

Therefore, the number of seats in each car is 6.
