11+14+25+-7+-9=34 34/5= 6.8
6.8 is the average
Here’s the answer. You just plug the y=-2+6 into -4x-6y=7.
8-15 is -7 and 8+(-15) is also -7 because this equation can also be written as 8-15 but I'm not really sure how to explain how they are different. Sorry

Answer:
M/N=5/8 or 62.5%
Step-by-step explanation:
when turning the word problem to equation...
![\frac{x}{y} \frac{80}{100}*M=\frac{50}{100}N\\\\ \frac{80M}{100}=\frac{50N}{100}\\ then you should criss-cross\\\100(80M)=100(50N) then you divide both sides by 100)\\80M=50N\\\\\frac{80M}{80}=\frac{50N}{80}\\ M=\frac{50}{80}=\frac{5N}{8}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D%20%5Cfrac%7B80%7D%7B100%7D%2AM%3D%5Cfrac%7B50%7D%7B100%7DN%5C%5C%5C%5C%20%5Cfrac%7B80M%7D%7B100%7D%3D%5Cfrac%7B50N%7D%7B100%7D%5C%5C%20%20then%20you%20should%20criss-cross%5C%5C%5C100%2880M%29%3D100%2850N%29%20then%20you%20divide%20both%20sides%20by%20100%29%5C%5C80M%3D50N%5C%5C%5C%5C%5Cfrac%7B80M%7D%7B80%7D%3D%5Cfrac%7B50N%7D%7B80%7D%5C%5C%20%20M%3D%5Cfrac%7B50%7D%7B80%7D%3D%5Cfrac%7B5N%7D%7B8%7D)
since you have the value of M in terms of N you should substitute M by 5N/8.
if you want it as a percent just multiply 5/8 by 100%.
![BY PERCENT=\frac{5}{8}*100%=\frac{500}{8}=62.5%](https://tex.z-dn.net/?f=BY%20PERCENT%3D%5Cfrac%7B5%7D%7B8%7D%2A100%25%3D%5Cfrac%7B500%7D%7B8%7D%3D62.5%25)
=62.5%
