Question 76536: A small company produces both bouquets and wreaths of dried flowers. The bouquets take 1 hour of labor to produce, and the wreaths take 2 hours. The labor available is limited to 80 hours per week, and the total production capacity is 60 items per week. Write a system of inequalities representing this situation, where x is the number of bouquets and y is the number of wreaths. Then graph the system of inequalities.
Here is what i have so far:
x=40 items * 1 hour = 40 hours
y=20 items * 2 hours =40 hours
So I have the 60 items and the 80 hours, but how do I write a system of inequalities representing this and then how do I graph it. See I'm trying.

Solve for x. Collect xs on the LEFT side. The solution should be presented with x first, the correct inequality symbol, then the number.
x + 4 – 8x – 1 > 3(x – 2)

Question 77974: -4>d-8
Can you help me break this down so I can understand it? I have a test tomorrow and my mind is blank. I think I go like this:
-4 -4 > d-8
then I'd have
0 > d-4
then
0x-4 < dx4 ..is this correct so far? Is that all? i think I'm supposed to draw a graph with this also.
Thanks,
Adam

Question 78550: I keep trying on this problem and I'm running out of time and sanity. Please for the love of God, help me. x5+24>3x3+8x2. I can't even figure out how to write it on the computer. That should be x to the power of 5, plus 24 > 3x to the power of 3 plus 8x squared. I understand that you need to bring everything over to equal 0. I have found one factor of it too, (x-2) but can't completely solve. Thanks so much!
