Let me help you with that :)

2x - 4 = - 10 + x (we transfer the x from the right side, and transfer the  - 4 from the left side)

2x - x = - 10 + 4 (we calculate this)

x = -6

And that is the answer; x = - 6 :)

St. Mary's Church is holding a raffle in which 1172 tickets have been sold at a cost of $2.00 each. Three prizes will be awarded
aleksandrvk [35]

Answer:

Step-by-step explanation:

Given that St. Mary's Church is holding a raffle in which 1172 tickets have been sold at a cost of $2.00 each.

Three prizes will be awarded: 1 for S500;1 for $250; 1 for $125.

Thus total number of tickets = 1172

Of these prize winning are 3

i.e. Tickets        Prize $     Net win amount            Prob       Net win amt*prob

         1                 500                (500-2) =448          1/1172           448/1172

         1                250                 (250-2) =248          1/1172           248/1172

          1               125                   (125-2) =123            1/1172          123/1172

       1169               0                    (0-2) =    -2             1169/1172    -2338/1172

Expected value = Total                                                                 -1519/1172

=-1.296
