Find the value of the variable and VW if V is between U and W.

UV=2,VW= 3x, UW=29
UV = r, VW = 6r, UW =42
UV = 4p - 3, VW = 5p, UW =15
UV = 3c+29, VW = -2c-4, UW = -4c

Need a site to explain how to do these.
Teacher not clear on explaining.

  • Geometry -

    UV + VW = UW

    8) UV + VW = UW
    2 +3x = 29
    3x = 27
    x = 3
    VW = 3x = 9

    9) UV + VW = UW
    r + 6r = 42
    7r = 42
    r = 6
    VW = 6r = 36

    10) UV + VW = UW
    4p-3 + 5p = 15
    9p = 18
    p = 2
    VW = 5p = 10

    11) UV + VW = UW
    3c+29 + -2c-4 = -4c
    c - 25 = -4c
    5c = 25
    c = 5
    VW = -2c-4 = -10-4 = -16
