“The captain of a rafting boat takes his crew down river for 6 hours, covering a total of 56 miles. When he realizes
he left one of his passengers behind, he is forced to paddle back upriver for 8 miles. The trip back up took him 3
hours."
A student used the following system of equations to model the situation given above. Which of the statements is
true about the system of equations the student used?
b = the speed of the boat
r = the speed of the current
8(6-r) = 3
16(6+r) = 56
A. The system of equations the student used is correct.
B. The top equation in the system is incorrect.
C. The bottom equation in the system is incorrect.
D. Both equations in the system are incorrect

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

answer: 1+1

step-by-step explanation: 1+1 is at least 2

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.
