Which question can be answered using the scientific process? O A. Should grocery stores be forced to use paper bags?
B. How much water does it take to make a plastic bag?
C. Should the government be allowed to ban plastic bags?
D. How should people be convinced to use plastic bags?

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
