A pair of boats costs $64.99. If the sales tax is 7%, what is the sales tax
on the boots?

First, you would need to find 7% of $64.99 which can be calculated like this:

64.99 x 0.07 = 4.55, this means that the sales tax on the boots is $4.55.

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)
