Answer:
the answer is 8
Step-by-step explanation:
i got this right on my question
2(-3)2 -5(4). -12 -20= -32. It's this because you plug -3 and 4 into x and y. Then if you answer it out it equals -32
2x + 5y = 270
Two times the amount of wheeled backpacks. Let x = wheeled backpacks.
Five times the amount of non wheeled backpacks. Let y = non wheeled backpacks.
Total backpacks will be 330 so 330 - 60 = 270
Therefore you get 2x + 5y = 270
