A bus makes a stop at 2:30, letting off 15 people and letting on 9. The bus makes another stop ten minutes later to let off 4 more people. How does the number of people on the bus after the second stop compare to the number of people on the bus before the 2:30 stop?

The original number of passengers on the bus decreased by 10 after the second stop.

Step-by-step explanation:

at 2:30:

15 passengers got off and 9 got on.

This means that the number of passengers = x - 15 + 9 ;number of passengers = x -6

10 minutes later:

4 passengers got off the bus

This means that the number of passengers = (x-6) - 4 ;number of passengers = x - 10

The original number of passengers on the bus decreased by 10 after the second stop

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
