1 answer:

3 0

This problem is really easy. You set up the first coordinate and then the midpoint on the bottom

(-9 , -6)
(7 , 2)

Now there are 16 steps from -9 to 7, then you add 16 more to 7 and you get 23 for the x axis.

There are 8 steps from -6 to 2, now count 8 more steps, and you get 10 for the y axis.

The coordinates of C are (23 , 10)
Hope it helped!

san4es73 [151]

Answer: An equation is *629 = n - 99. The geometry book has 728 pages*

Step-by-step explanation: The Algebra book has 99 pages LESS than the geometry book, in other words, the geometry book has 99 pages MORE than the Algebra book. This equation can be used to find the answer. I’m afraid 530 is not the answer.

Hope this helps! :)
