These are linear equations that can be solved simultaneously;
5m+3n=41
3m-6n=9 (multiplying the first equation by 3 and the second by 5)
15m+9n=123
15m-30n= 45 (subtracting the two equations)
39n = 78
n = 2,
and for m, 3m = 9+6(2)
= 21
m = 7
Therefore, n=2 and m=7
Answer:
this is not an answer sorry, but someone answered me with a link and I opened it and it virused my phone
It would be -7f degrees because -14-7 would equal -7
Answer:
2.25
Step-by-step explanation:

it is 1.5 mi from kelvins door to the park, it is 2.25 mi from kelvins house to the library.
hope this helps, let me know if you need more explaining
20x+30y= c(total cost of money)
Part B: 20(10)+5(30)
200+150=$350
