For the answer to the question above, 
and we are told that there are "four times as many quarters as nickels"
this translates to
q = 4n

0.05n + 0.25q = 2.10
and
q = 4n
are your two equations that could be used to solve this problem


if you would like to know how many nickels and how many quarters there are, plug in q = 4n into the first equation and get
0.05n + 0.25(4n) = 2.10
then I would stop here
because I didn't see the choices. So the answer is 4n

What expression is equivalent to m-4/m+4 divided by (m+2)
Ilya [14]
The first answer is correct coz ( for instance ) ‘x’ is divided by ‘y’ then this is similar to the x multiples by 1/y

So in that case, if we apply the same analogy to this question then the answer would be m-4/(m+4) ( m+2)
