Together the Yankees and Red Sox have won 30 World Series in the last 100 years. The Yankees have won 9 times as many as the Red Sox. How many World Series have the Yankees won?

Respuesta :

y=9r, r=r

9r+r=30
10r=30
r=30/10
r=3(Red Sox)

yankee=9(3)=27
the answer is 270 , because the problem says 9 Times as the Red Sox , and 30 times 9 equals 270
