6. protein bars come in a 4-pack box or 12-pack
box. the 4-pack costs $7.68 and the 12-pack
costs $22.32. which box is the better value

The 12 pack has a better value.

Step-by-step explanation:

1. create a ratio table.

you want to know how much the 4 pack would cost if it was a 12 pack.

you can see the ratio table in the picture above.

As you can see, when the 4 pack equals $7.68, making it a 12 pack will equal $23.04.

Then, compare 23.04 to 22.32.

In conclusion, the 12 pack has a better value.

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)
