Honestly no idea... sorry
Answer:
I cant see the image it doesnt seem to be loading but here is how to do the problem-->.
Add both the x coordinates and divide by 2 (this is the new x coordinate for the midpt)
next:
Add both y coordinates and divide by 2(this is the new y coordinate for the midpt)
Step-by-step explanation:
Let
x------> the number of multiple choice question
y------> the number of free response question
we know that
-----> equation A
-----> equation B
Substitute equation B in equation A
![3[15-y]+8y=55](https://tex.z-dn.net/?f=3%5B15-y%5D%2B8y%3D55)
Find the value of x
therefore
<u>the answer is</u>
the number of multiple choice question are 
the number of free response question are 
Answer:
See below
Step-by-step explanation:
Assuming a number line:
rs + st = rt
3x-16 + 4x-8 = 60
7x -24 = 60
7x = 84
x = 12
