Answer:
10. Statement: Point P lies on line C'D'. Reason: The coordinates of P satisfy the equation of line C'D'.
Step-by-step explanation:
The equation for line C'D' in statement 8 appears to be in error. It should be ...

The coordinates of point P given in statement 9 are in error (they cannot be negative). They should be ...
P = (2/3(r+t), 2/3s) . . . . . without the minus signs
This point will satisfy the equation of line C'D'. Here is the algebra. (Notice we have multiplied each term on the right of the above equation by (-1/-1).

So, step 10 should say, in effect, P lies on C'D'.

<em>Comment on the proof</em>
IMO it is unfortunate that this proof has so many mistakes. Properly done, it is a nice demonstration that the medians are concurrent. It also demonstrates that the location of the centroid is 1/3 of the distance along the median toward the vertex.
2,3,5,6,7,8 IM sorry if its not the answer u were asking for
we know that
1) Mailyn can eat 32 cookies in an hour
1 hour is equal to 60 minutes
<u>Find how cookies eats Mailyn in one minute</u>
by proportion

2) Juan needs 3 hours to eat 32 cookies
<u>Find how cookies eats Juan in one minute</u>
by proportion

<u>3) Find how long will it take them to eat 40 cookies together</u>
we know that
Maylin and Juan eats in one minute together ---------> (0.53+0.18)=0.71 cookies
so
by proportion

therefore
<u>the answer is</u>
