Answer:

x = 6, BC = 60

Step-by-step explanation:

6x + 2x + 1 = 81

8x + 1 = 81

8x (+ 1 - 1) = 81 - 1

8x = 80

8x/8 = 80/8

x = 10

6x

6(10) = 60

Kobe has collected 750 football cards and 660 baseball cards. He wants to divide them into piles so that each pile has only one
Harrizon [31]

Answer: 30 cards

Step-by-step explanation:

To find the greatest possible number of cards in each pile such that there is the same number of cards in each​ pile we need to find the greatest common factor of 750 and 660.

Using Euclid division method , we have

750=1(660)+90\\\\660=7(90)+30\\\\90=3(30)+0

Hence, the greatest common factor of 750 and 660 = 30

Thus, there will be 30 cards in each pile.
