It took alice 6 5/6 hours to drive to her grandparents' house for . on the way home, she ran into traffic and it took her 8 2/9 hours. how much longer did the return trip take?

Time taken to drive to her grandparents house = 6 5/6  hours

We convert this mixed into improper fraction, we get = 41/6 hours

Time taken to drive to her grandparents house = 41/6 hours

Time taken to drive back = 8 2/9 hours

We convert this mixed into improper fraction, we get = 74/9 hours

Time taken to drive back = 74/9 hours

Difference between the two = 74/9 - 41/6  = (148-123)/18 = 25/18 hours = 1 7/18 hours

Therefore it took 1 7/18 hours longer to drive back.

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
