What i understand from the statement given is that the expression will be:
10m + n/4
where m = 5 and n = 16
now by putting the values of m and n in the expression,we get
10(5) + 16/4
=50 + 4
= 54
Thus, after solving the expression we get the answer 54.
Yes it would be okay. You are only using it for 2 things. Not everything.
Gouache is a type of watercolor in which white pigment is added, creating a duller effect and a tinted feel with a smooth finish. The paint usually comes in tubes, with which the artist must add the vehicle (water).
