What is the total cost of a pair of jeans that are priced $50.00 if there is 7% sales tax?
$53.75
$55.50
$57.50

The answer is $53.50

Step-by-step explanation:

Add 100% and 7%

Then multiply 107% times 50 because you have to pay the full price which is 100%, plus sales tax which is the 7%.

there is no grid

step-by-step explanation:

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)
