Sue is 20 feet below sea level in a cavern. She climbs up out of the cavern
35 feet directly up a mountain. Where is Sue on the mountain? Write as a
integer
Your answer

the answer is 15

Step-by-step explanation:

because 30 - 20 = 10

10 + 5 = 15

and 15 is an integer

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
