During a baseball season, team a scores 9 runs for every 7 runs that team b scores. The total number of runs scored by both team
mrs_skeptik [129]

Answer:

∴ Team b scores is 630

And team a scores is 810

Step-by-step explanation:

Given;

Team a scores 9 runs for every  7 runs that team b scores.

Lets,

Think b is scores  x runs;

Then a is scores x+(2\times\frac{x}{7} );

Because every 7 runs of b , a is scores more 2 runs.

Total number of runs scored by both teams is 1440

Runs score by team a + Runs score by team b=1440

x+(2\times\frac{x}{7} )+  x =1440

2\times x+ \frac{2\times x}{7}=1440

\frac{(14\times x)+(2\times x)}{7} =1440

\frac{16\times x}{7} =1440

16\times x=1440\times 7

x=\frac{10080}{16}

x=630

∴ Team b scores is 630

And team a scores is 630+(2\times \frac{630}{7} )=810
