Complete question :

Jason purchased a pack of game cards that was on sale for 13% off. The sales tax in his county is 8%. Let y represent the original price of the cards. Write an expression that can be used to determine the final cost of the cards.

A) y − 0.13y

B) 1.08(0.87y)

C) 0.08(0.87y)

D) y − 0.87y + 0.08y

1.08(0.87y)

Step-by-step explanation:

Let initial cost = y

Cost on sale = 13% off

Discounted price = y - 0.13y = 0.87y

Sales tax on purchase = 8%

Sales tax is ade d to the purchase price of item, hence ;

Sales tax = 1 + 0.08 = 1.08

The final cost of card is:

Sales tax * discounted price

1.08 * 0.87y

1.08(0.87y)

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)

answer: group b.
