Answer:
the answer would be n+5
Step-by-step explanation:
5n is the same as saying 5 multiplied by n
n +5 would equal the same number
for example if n=2 then 5+2=7
and if we used n+5 it would be 2+5=7
and if you plugin n=2 for all the equations the only correct one is N+5

Answer:
As the cars speed the loudness decreases for you to not really hear anything
We do like the following:
Set the first number is a and the second is b.
We have two equations: a+2xb=24, 2xa+b=21
And we have 2xa+4xb=48 or 2xa=48-4xb
So: 48-4xb+b=21 or -3xb=21-48=-27 and we got b=-27:(-3)=9 and a= 6
a=6 and b=9
