F is between C and B. If CF = 7x+4, FB = 10x -69, and CB = 12x -25. Find x and CF

Step-by-step explanation:

  CF + FB = CB

  (7x+4) +(10x-69) = (12x-25)

  5x = 40 . . . . . . . . add 65-12x

  x = 8 . . . . . . . . . . divide by 5

  CF = 7x +4 = 7(8) +4 . . . . use the x value in the expression for CF

  CF = 60

Kim rolls a dice and flips a coin.

For coin: we have either H or T  

For dice: we have 1, 2, 3, 4, 5 or 6

On a coin, the probability of heads:  

On a dice, the probability of getting 2 :

Hence, the probability of getting a 2 and a head is

=

So, the probability that Kim gets a 2 and a head is
