Harry uses a wheelbarrow to haul wood from his backyard, to the back of his neighbors house, located 1680 CENTIMETERS away. If he takes one break in the Middle when pushing the wheelbarrow the complete distance, at what distance does he take his break? If harry has 72 pieces to take , but can only take 8 each time, what distance in METERS, will he travel to move all the

42

step-by-step explanation:

i believe a. 12x≥120 is the answer

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.
