Answer:
6.2 seconds
Step-by-step explanation:
To translate into math, the question is asking you "for what approximate t value does h = 0?" In order to solve, you can plug in 0 for h and solve for t.
0 = -16t^2 + 620
-620 = -16t^2
620 = 16t^2
38.75 = t^2
= t
6.2 ~~ t (rounding to the nearest tenth)

2(2x - 5) = 3x + x - 2x
Distribute the 2.
4x - 10 = 3x + x - 2x
Combine like terms.
4x - 10 = 2x
Subtract 4x from both sides.
-10 = -2x
Divide by -2.
5 = x
x = 5
