Answer:
least to greatest : -54 , -3/9 , 9/5 , 6.6 , 75,
<span>3(2x+4y-2z)+7(x+y-4z) =
3*2x + 3*4y - 3*2z + 7x + 7y - 7*4z =
6x + 12y - 6z + 7x + 7y - 28z =
(6+7)x + (12+7)y + (-6-28)z =
13x + 19y + (-34)z =
13x + 19y -34z;

6/15 = 2/c...this is a proportion, so we must cross multiply
(6)(c) = (15)(2)
6c = 30..divide both sides by 6
c = 30/6
c = 5
and if u will notice...6/15 = 2/5...proportions are nothing but equivalent fractions.
