Can you guys ! i am pretty confused by this question!

Doreen is 3/4 mile from the Library.

Sheila is 1/3 as far as Doreen.

well, what's 1/3 of 3/4?  well, is simply their product, so (1/3) * (3/4) = 1/4.

meaning Sheila is 1/4 mile as far as Doreen.

well, Doreen is 3/4 of a mile away, so Sheila is then 3/4 + 1/4 = 1 whole mile away from the Library.

is Sheila farther than Doreen from the Library?

of course, 1 mile > 3/4 mile.

does Sheila live 1/4 of a mile from the Library?

well, you already know how far Sheila is, check above.

is Sheila twice as farther than Doreen?

Doreen is 3/4 mile away, Sheila is 1 mile away, 1 mile is not twice as much of 3/4.

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
