While exercising cody traveled 4 2/7 kilometers. if he walked 2 3/9 kilometers and jogged the rest, how many kilometers did he jog

41/21km or 1 20/21km

Step-by-step explanation:

1) simplify fractions: 4 2/7 = 30/7 and 2 3/9 = 7/3

2) find common denominator: 90/21 - 49/21

3) subtract: 41/21

4) simplify: 41/21 or 1 20/21

Step-by-step explanation:

y/x=18

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)
