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:
Step-by-step explanation:
8 (x -3) +7 = 2x (4 -17)
8(x -3) +7 = 2x (-13) here was the error because the had 13 that is incorrect
8x -24 +7 = -26x
8x -17 = -26x
-17 = -26x -8x
-17 = -34x
-17/-34 = x
1/2 =x
Answer: 6.
Step-by-step explanation:
4^2 = 16
10 − 16 + 6 * 2
6 * 2 = 12
10 − 16 + 12
10 - 16 = -6
-6 + 12 = 6
Answer:
22801
Step-by-step explanation:
#40
No. of terms = (301 + 1)/2
No. of terms = 302/2
No. of terms = 151
Now,
Sum = n²
Sum = (151)²
Sum = 22801
