The senior class at High School A and High School B planned separate trips to New York City. The senior class at High School A rented and filled 3 vans and 3 buses with 213
students. High School B rented and filled 8 vans and 7 buses with 511 students. Each van
and each bus carried the same number of students. Find the number of students in each van
and in each bus.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

table 3 represents a direct variation function. : )

inverse operation of addition

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
