X/6 + 7 = 20
subtract 7 from each side
x/6 + 7 - 7 = 20 - 7
x/6 = 13
multiply each side by 6 to get x alone
x/6 • 6 = 13•6
x = 78
To get the total number of games possible, we will use the combination formula.
Total number of games :

= 45
Total of 45 games in the whole tournament.
Meanwhile, if there would be boy-versus-boy, we will have

The answer is 10.
The fraction for boy-versus-boy game will be
10/45 or 2/9 when simplified.
The exponent would b 15
U just gotta solve it than u get 3375 than look for the square root of that and it’s 15over15
