There would need to be nine.

Step-by-step explanation:

4 x 5 = 20 5 cars is to little of a umber

4 x 7 = 28 close

4 x 8 = 32 8 cars carry 32 people but there is one student left out of that car so they would need an extra car.

The the goes "Well.... flop. I'm alone"

So nine cars.

Answer:

x = 20

Step-by-step explanation:

If two lines are cut by a transversal and the corresponding angles are congruent, the lines are parallel.

$\rm \longrightarrow \angle 2 = \angle 5 \\ \\ \rm \longrightarrow 3x - 20 = x + 20 \\ \\ \rm Add \ 20 \ both \ sides: \\ \rm \longrightarrow 3x - 20 + 20 = x + 20 + 20 \\ \\ \rm \longrightarrow 3x = x + 40 \\ \\ \rm Substrate \ x \ from \ both \ sides: \\ \rm \longrightarrow 3x - x = x - x + 40 \\ \\ \rm \longrightarrow 2x = 40 \\ \\ \rm Divide \ both \ sides \ by \ 2: \\ \rm \longrightarrow \frac{ \cancel{2}x }{ \cancel{2}} = \dfrac{40}{2} \\ \\ \rm \longrightarrow x = 20$
