Answer:

Step-by-step explanation:

11. 76x + 23x = 33

99x = 33

x = 33/99 which reduces to 3

12. 140r - 8r - 4r = 216

128r = 216

r = 216/128 which reduces to 27/16

13. 98c - 99c = 1

-1c = 1

c = -1/1

c = -1

14. 104mn + (-84mn) = 36

104mn - 84mn = 36

20mn = 36

mn = 36/20 which reduces to 9/5....I am not sure about this one...I was not sure if u were looking for m or n..so I didn't separate them. But if ur looking for m, it is m = 9/5n...and if ur looking for n, it is n = 9/5m

15. 118j - 234j = 234

- 116j = 234

j = -234/116 reduces to - 117/58

Aleksandr [31]

Answer:

so this would be the equation

2(2*10)=v

So the number on the outside is the number of stands, the second 2 is for the two rows, and the 10 is the games. I did this because its two rows and combined they make 20 games. It took me a little to figure that out.

This shows the number of games total in both holders.
