Okay so I'm going to set up a equation:
5.27= 3.40+ 0.85x, we have our total our price of one pineapple and our variable
next I isolate the variable:
5.27-3.40=0.85x
next:
1.87=0.85x
x= 2.2
she bought 2.2 pounds of tomatoes
What I would do is subtract 12 from -5. Then you would have -17. Then you would add 4 and it would be -13. So your answer is:
<h2><em>
-13</em></h2>
Its D. x = 2, y = -8
6*2 + (-8) = 12 - 8 = 4
