Aschool is planning a field trip for 142 people. the trip will use six drivers and two types of vehicles : buses and vans. a bus can seat 51 passngers. a van can seat 10 passengers. write and solve a system of equations to find how many buses and how many vans will be needed

Step-by-step explanation:

The trip will use six drivers therefore

x+y=6

51x+10y=142 (A bus can seat 51 passengers. A van can seat 10 passengers.)

10x+10y=60

41x=82

x=2 buses

y=4 vans

Got it?

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
