First subtract 100v² from both sides to get:
C²L²=100c²-100v²
Then divide both sides by C²:
L²=(100c²-100v²)/C²
Then take the square root of both sides:
L=+ or - the square root of (100c²-100v²)/C²
The answer you selected is correct
3x - 4y = 16
3x = 4y + 16
x = 4y/3 + 16/3
The tank is filling at
the rate of (58-36) in/(5-3 h) = 22/2 = 11 in/h.
72-58 = 14 inches more
to fill
<span>
The remaining 14 inches will be filled in
14 /11 = 1.27 , round to 1.3 hours</span>
so total time
would be 5 +1.3 = 6.3 hours
