Erika has 3 pieces of ribbon. each piece is 25 yards long she needs to cut pieces that are 22 inches long . what is the greatest number of 22-inch pieces that she can cut from the three ribbons ?

120 pieces.

Step-by-step explanation:

We know that 1 yard = 36 inches

Given: The length of each piece of ribbon= 25 yards

If she needs to cut 22 inches long pieces, then the total number of pieces cut from 1 ribbon

Thus, the total number of pieces she cut from 3 ribbons

Hence, the greatest number of 22-inch pieces that she can cut from the three ribbons =120

step-by-step explanation:

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)
