Respuesta :
x = the number of games won
y = the number of games lost
A baseball team played 140 regular season games:
x + y = 140
The ratio of wins to lost was 5/2 means:
x : y = 5 : 2 cross-multiply
5y = 2x
x + y = 140
5y = 2x
x = 100 games won
y = 40 games lost
The team won 100 games and lost 40 games.
