Answer:

Step-by-step explanation:
For this case we know that we have 12 cards of each denomination (hearts, diamonds, clubs and spades) because 12*4= 52
First let's find the number of ways in order to select 5 diamonds. We can use the combinatory formula since the order for this case no matter. The general formula for combinatory is given by:

So then 12 C5 would be equal to:

So we have 792 was in order to select 5 diamonds from the total of 12
Now in order to select 3 clubs from the total of 12 we have the following number of ways:

So then the numbers of ways in order to select 5 diamonds and 3 clubs are:

Answer:
x = 6

Answer:
12
Step-by-step explanation:
Change 3/4 to 12/16 by multiply both side by 4 (common denominator)
12/16 divide by 1/16 is 12.
= 3m-10m - 20 + 1/5
= -7m - 19 4/5
