The answer is 12.24745 or 5/6
The height of the baseball going upwards is 35.77 ft
<u>Explanation:</u>
Given:
initial velocity, u = 48 ft/s
Height, h = ?
If the ball is thrown in the air, then the final velocity of the ball will be 0 as the ball later comes to rest.
Acceleration of the ball will be acceleration due to gravity
g = 9.8 m/s²
g = 32.2 ft/s²
We know,
(v)² - (u)² = 2gh
(0)² - (48)² = 2 X 32.2 X h
2304 = 64.4 X h

Therefore, height of the baseball going upwards is 35.77 ft
First, distribute
3(x-7)=3x-21
3x-21-x=2x-21
3x-1x-21=2x-21
add like terms
2x-21=2x-21
minus 2x oth sides
-21=-21
true
we see that the x's wil cancel
therfor x=all real numbers
