Answer:
-7.5x3+(20+2.5)=0
this one is equal to 0 ;)
the volume of the cone would be 2.36 I hope this helps ❤️
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
