Answer 1

The Rattlesnakes must win their next 9 games in order to have an 80% winning percentage.

Hope this helps.

Answer 2

Answer:

$0.80=\frac{3+x}{6}$

Step-by-step explanation:

Given,

The Rattlesnakes have won 3 games out of 6.

So, the ratio of his winning games out of total games = $\frac{3}{6}$

Let x be the number of consecutive games the Rattlesnakes must win in order to increase their winning percentage to 80%,

That is,

$\frac{3+x}{6}=80\%$

$\frac{3+x}{6}=0.8$    ( 1 % = 0.01 )

Which is the required equation.
