Tell what each expression represents, and what the variable stands for in each expression. Please help form the expression. Thx

  1. Reiny

    Meg --- m
    Jill --- m-2
    Beth = (1/2)(m)
    = m/2 or
    = (1/2)m

    other possibly:

    let Jill be x
    Meg --- x+2
    Beth --- (x+2)/2 or
    = x/2 + 1 or
    = (1/2)x + 1

    try it by letting Meg = y
