    sorry but i need quick help alagebra and equations

    you fill an empty hot tub that is 54 inches tall. you started putting water in at 11 am and check to find 2 inches of water in the tub. you check again at 1 pm to find 5 inches total of water.
    assume the water will fill at the same rate.
    1. how many inches of water will be in the hot tub at 5 pm?


    EDIT:you have 100 tickets, you are selling them at a rate of 10 per week. each is 50 cents.
    1. write an equation to detemine the total value of the reamining ticketss after w weeks.
    -----------------------------------------------------------------------

    solve for x:

    3(x+2)=5

    6=-2(8x-4)

    -2(-4x+7)=18

    sorry but my teacher is a meanie who wont help me.

    Hi enyaz11,

    I'm sorry, but where did the 2 inches of water come from? If you started filling at 11 am, at what time did you check to find the 2 inches of water? At 1 pm (2 hrs later), you measured 5 inches in the tub. So, you are either putting 3 inches or 5 inches of water in every 2 hrs. You have a span of 6 hours from 11 am to 5 pm, so go figure.

    v = .50(100-10w)

    3x = -1
    x = -1/3

    6=-2(8x-4)

    6 = -16x + 8
    -2 = -16x
    1\8 = x

    x = 1/8

    -2(-4x+7)=18

    8x - 14 = 18
    8x = 32
    x = 4

    (S)he's probably not. Show more initiative. Be respectful above all else.

    Do you do anything to help yourself or are you a "meanie" too?

    In other words, what have you done on these?
