A roller coaster has 4 cars, each with the same number of seats. There are 21 passengers seated in the roller coaster, but 3 seats are empty. Write an equation that can be used to determine the number of seats in each car, s.

Step-by-step explanation:

Given

Required

Equation for the number of seats

Represent number of seats in 1 car with x

seats

Solving further:

Number of seats can be determined using the following logic;

The occupied seats are occupied by passengers;

So:

becomes

Hence; total seats in the 4 cars is 24

Recall that:

seats

Substitute 24 for 4 cars

Reorder

step-by-step explanation:

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
