Step-by-step explanation:

Giving the following information:

A shop sold 250 CDs last week. The sales of CDs increased by 16% this week.

To calculate the number of CDs sold this week, we need to use the following formula:

Cds sold= Cds sold last week*(1 + percentage increase)

Cds sold= 250*1.16

Cds sold= 290

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)
