Answer:

First two boxes are 6

Third box is -18

the last row is 3/1 (-18/1) = (1/3a) 3/1

Step-by-step explanation:

Ima try my best to explain:

-6 = 12 + 1/3a

+6 +6

0 = 18 + 1/3 a subtract 18 on both in order to get 1/3a by itself

-18 -18

-18 = 1/3a

-18/ 1/3 = 1/3a / 1/3 to make it easier multiply by the reciprocal on both sides

3/1 x -18/1 = 1/3 x 3/1

multiply across will get you -54/1 which is just -54

Answer:

1/13, 12/13

Step-by-step explanation:

There are 4 aces in a 52 card deck so P(Ace) = 4 / 52 = 1 / 13.

There are 52 - 4 = 48 cards that are not aces out of the whole 52 cards in the deck so P(not Ace) = 48 / 52 = 12 / 13.
