    Friends homework, been awhile
    Leah makes $24 per hour for a 40-hour week and time and a half for every hour over 40 hours. If she made $1140 last week, how many overtime hours did she work?

    Four less than nine times a number is one hundred twenty-two. Find the original number.
    The cost of renting a subcompact car from Super Rental is $20 a day plus 25 cents per mile. How far can Allison drive in one day if she has only $75?

    The length of a rectangular field is 50 meters more than twice its width. If the perimeter is 700 meters, find the dimensions of the field.

    A wire measures 84 centimeters in length. It is cut into two pieces. The shorter piece is 6 centimeters shorter than the long piece. Find the length of each piece.

    Create a real-life problem that involves linear equations and provide a solution to the problem.

    If anyone can help with any of these questions I would really appreciate it, it's been a long time since I have had to do this

    You can see it better if you draw a picture. Slap the person who yelled at you.

    Draw a picture--a rectangle--then note on each side the values assigned.

    (I figured it out ten minutes ago.)

    rectangle - 4 sides, 2 shorter (x) and 2 longer (2x + 50)

    Okay I got the picture drawn

    perimeter is short side + long side + short side + long side = 700 m.

    picture is of a rectangle - 4 sides, 2 shorter (x) and 2 longer (2x + 50)

    What did you get so far? Name the value for each side.
  • Aug 8, 2009, 03:21 PM

    375 for the length and 275 for the width?
  • Aug 8, 2009, 03:23 PM
    Romefalls19
    162.5+162.5+137.5+137.5?

    no

    x for each short side
    2x+50 for each long side

    x + x + 2x + 50 + 2x + 50 = 700 m.
  • Aug 8, 2009, 03:29 PM

    OK so then after I simplify, would it be

    x+x+2x+2x=600?

    Yes, then solve for x, the short side.

    After that, you can calculate the long side, 2x+50.

    Tell me your answers.

    x+x=300?

    I am just trying to see if I'm on the right track lol

    You got derailed.

    1x + 1x + 2x + 2x = 600 m.

    ADD the x's.

    To check your work:

    100 + 250 + 100 + 250 = what?

    Don't forget to put the meters or feet or dollar signs or whatever on the answers.

    48 is the longer piece

    x + x-6 = 84 cm.
    2x = 84 + 6
    2x = 90
    x = 45

    thus x-6 =??

    Don't forget the cm.

    Yeah she understands how we got those answers, we had to isolate x to find the answer.

    Is it 220mi?
