Answer:

Explanation:
The given addition exercise is:

The LCM of the denominator (5 and 3) = 15
Multiply 2/5 by 3/3

Multiply 1/3 by 5/5

The addition becomes

Therefore, we can fill in the vacant boxes as shown below:


the discriminant is a negative value, thus no solution for such quadratic, meaning if we use h=64.5 like we did, there's no "t" seconds at which point the ball hits the batting cage.
Any point with the y of 5 could be the answer
Answer:
r = t - u - s
Step-by-step explanation:
To solve for r in terms of s, t, and u, means to have r on one side and have t, u, and s.
t = u - s + r
t - u = s + r
t - u - s = r
