Percent formula : is / of = % / 100
12 is ? % of 200..
is = 12
of = 200
% = x
now sub and solve
12/200 = x / 100
cross multiply because this is a proportion
(200)(x) = (12)(100)
200x = 1200
x = 1200/200
x = 6.......so 12 is 6% of 200 <==

Answer:
-6c + 7
Step-by-step explanation:
To simplify this expression, you must add like terms. Because 3c and -9c both have the same variable (c), they are like terms.
3c + (-9c) = -6c
The 7 stays the same, so the simplified expression is -6c + 7.
Hope this helped :)
