You do
5x2/3
5x2 /3
10/3
3 1/3 is your answer.
So, we have the unknown value, let's call it "x".
95% is .95 as a decimal.
So, let's find what .95*350 is.
.95*350=332.5
So, the unknown value is 332.5.
332.5 is 95% of 350.
5x-3=21-x
6x=24
X=4
You simply have to isolate the variable and then divide by 6 so that x is completely alone.
So,
720 pt./hr.
2 pt. = 1 qt.
720/2 = 360
360 qt./hr.
Now, since there are 60 mins. in 1 hr., multiply the number by 60.
360(60) = 21600
720 pt./hr. = 21,600 qt./min.
Sqrt(-2), can be written as i * sqrt(2). Thus, our answer is x - i sqrt(2).
