Three friends each have some ribbon. carol has 90 inches of ribbon, tino has 4.5 feet of ribbon, and baxter has 5.5 yards of ribbon. express the total length of ribbon the three friends have in inches, feet, and yards. inches = feet = yards

inches= 342''

feet= 28.5'

yards= 9.5 yds

Step-by-step explanation:

inches= 90 +54 + 198= 342''

feet=342*(1/12)= 28.5'

yards= 9.5 yds

step-by-step explanation:

1+1=2

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)
