Answer:
Step-by-step explanation:
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
equate to zero
so
substitute in the formula
It would be: Kn + 4f = 9
kn = 9 - 4f
n = (9-4f) / K

We can rewrite the given time as:
- 7.03x10^15 mins
- 1.17x10^14 hours.
- 4.88x10^12 days.

What is 4.22x10^17 seconds in minutes and hours?</h3>
First, remember that:
60s = 1 min
Then to write that amount in minutes, we just need to divide by 60, so we get:
(4.22x10^17)/60 mins= 7.03x10^15 mins
Now, remember that:
1 hour = 3600s
Then to get the time in hours, we need to divide by 3600:
(4.22x10^17)/3600 h = 1.17x10^14 hours.
Similarly, you can change to any time unit that you want, for example:
1 day = 24*3600 s
Then the time in days is:
(4.22x10^17)/(24*3600) days = 4.88x10^12 days.
And so on.

0.3x = 0.2 - 0.2x
0.5x = 0.2
x =0.2/0.5 = 2/5
