First u have to move the -5/2 to the other side. Sou add 5/2 to -5/2, which cancels out. Then ur stuck with x=9+5/2. Next u solve. 9+2.5=11.5. so ur answer is 11.5

On a baseball
vampirchik [111]

Based on the distance of the pitcher's mound from the home plate, the path of the ball, and the height the ball was hit, the distance the outfielder threw the ball is C. 183.0 ft.

<h3>How far did the outfielder throw the ball?</h3>

Based on the shape of a mound, the law of cosines can be used.

The distance the ball was thrown by the outfielder can therefore be d.

Distance is:

d² = 60.5² + 226² - (2 x 60.5 x 226 x Cos(39))

d ²= 33,484.42ft

Then find the square root:

d = √33,484.42

= 182.9874

= 183 ft

Barrett has 20 quarters.
