Step-by-step explanation:
So I think that number 6 is just dividing by 3 and the second one doesn't like divide so number 7 is no and number 6 is yes
Let
x------> the number of multiple choice question
y------> the number of free response question
we know that
-----> equation A
![x+y=15](https://tex.z-dn.net/?f=x%2By%3D15)
-----> equation B
Substitute equation B in equation A
Find the value of x
![x=15-y](https://tex.z-dn.net/?f=x%3D15-y)
![x=15-2=13](https://tex.z-dn.net/?f=x%3D15-2%3D13)
therefore
<u>the answer is</u>
the number of multiple choice question are ![13](https://tex.z-dn.net/?f=13)
the number of free response question are ![2](https://tex.z-dn.net/?f=2)
The equation would be 4y=5x 4(x+15)=5x x+15=y
let x be the amount that Shelia deposits each time
let y represent the amount that Sherri deposits each time
4(x+15)=5x
4x+60=5x
-4x -4x
60=x
Check:
x+15=y 60+15=y y=75
4(75)=5(60)
300=300
Shelia deposits $60 each time.
3x + 5y = -2
3x + 7y = 26
Subtract first equation from second
2y = 28
y = 14
Plug it in
x = -24
