Aclass of 195 students went on a field trip. they took 7 vehicles, some cars and some buses. find the number of cars and buses taken if each car holds 5 students and each bus holds 45 students.

solve and show equations along with work, giving 95 points to the correct answer.

The number of cars taken: 3

The number of buses taken: 4

Step-by-step explanation:

Lets b = # of buses and c = # of cars

b + c = 7  > b = 7 - c

45b + 5c = 195

Substitute b = 7 - c into 45b + 5c = 195

45(7 - c)+ 5c = 195

315 - 45c +  5c = 195

315 - 40c = 195

-40c = -120

    c = 3

    b = 7 - 3

    b = 4

The number of cars taken: 3

The number of buses taken: 4

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal
