Fred is playing tennis. for every 2 of his serves that land in, 4 serves land out. if he hit 28 serves in, how many serves landed out?

2 for every 4 = 1 for every two, so 28 multiplied by two. Your answer is 56.

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)

it shoild be o
