a=90 degrees divide by 5

=18 degrees

2c+a=90

2c+18=90

2c=90-18

2c=72

divide each side by 2

c=36

therefore:

2c=72

b=4a+c

b=4(18)+36

b=72+36

b=108

Plz some one help me

sveta [45]

9 games

You can get this by multiplying each percentage by the total number of games to see what they have to expect.

.55*180 = 99 games (red team)

.60*180 = 108 games (blue team)

Now subtract the blue team expectation from the red team.

108 - 99 = 9 games.
