Tickets to King Middle School play cost $1 for King students and $3 for everyone else. Rose, a student at King Middle School, went to the play with friends from another school. the group paid a total of $13 for the tickets. How many friends went to see the play with Rose?

Answer must include a Let Statement, an equation, a proper solution (using Properties of Equality).

Would this answer be correct ?
Let X=friends

3a + 1 = 13
3a = 13-1
3a = 12
12/3 = 4

4 friends went to see the play with Rose

    yes you are correct

    You could have checked your answer by simply working it out with your answer

    what is 1 + 4(3) ???

    I know, but wanted to be sure about the let statement, equation parts they were asking for. Thanks.

  • Math -

    Your "let" statement should be a complete English sentence with proper grammar

    e.g.

    let the number of friends that went with her be x
    3x + 1 = 13
    3x = 12
    x = 4

    So , four friends went with her.

    Ok.. Can u check these for me too please?

    Rename each repeating decimal as a fraction in lowest terms. Using let statement, an equation, a proper solution (using properties of equality)

    1) 0.87 (repeating nos are 87) So..
    Let  X =    0.87
    100X = 87.87
    -      X =      0.87
    ____________
    99X/99 = 87/99
    X= 29/33

    2) 0.5406 (repeating nos are 06)  So...
    Let           X = 5406
    10,000X = 5406.5406
    -               X = 0.5406
    ________________________
    9999X/9999 = 5406/9999
    5406/9999 = 1802/3333
    X= 1802/3333

    3) 0.048 (repeating no is 8). So...
    Let X =    0.048
    1000X = 48.8
      -100X=   4.8
    _______________________
    900X/900 =  44/900
    X=11/225

    4) 3.274 (repeating nos are 74)
    I really don't get this one

    #2 is not correct, you should have checked your answer with a calculator

    Here is the way I would do that one

    let x = .54060606...
    times 100, since 2 digits repeat
    100x = 54.060606
    subtract
    99x = 53.52 , make sure you line up the decimals in the subtraction to see how I got that
    x = 53.52/99 = 5352/9900
    now reduce ...
    = 446/825

    on calculator: 446/825 = .54060606...

    #4.
    3.274 , just work on the decimal part

    let x = .274747474..
    times 100 , (remember why ? )
    100x = 27.47474...
    99x = 27.2
    x = 27.2/99 = 272/990 = 136/495

    now don't forget about the original whole number in front
    3.274 = 3 136/495 as a mixed number
    or
    1621/495 as an improper fraction

    check: 136/495
