D because 2/3 of the cards are odd and 64 is 2/3 of 94

Using a Ratio to solve

If we have a ratio of 7/12 odd cards to total cards she can expect to pull out 7 odds in her 12 cards. Now we will use this ratio out of 96 cards. If we have 96 cards with a 7/12 ratio we will divide 96 by 12 which is 8. Now we use our 8 and will multiply it by 7 which is our odd cards. Our total number of odds pulled out of 96 cards will be 56 out of 96.

Solve for x 9(x-1) = 2
Katen [24]

Answer: x = 9/11

Step-by-step explanation:

First, distribute 9 to x and -1

9x - 9 = 2

Then add 9 to both sides

9x = 11

Then divide both sides by 9

x = 9/11

Hope it helps :)
