Aroller coaster can take 162 passengers around the track in 9 mintues. the coaster operates at a constant rate.
how many passengers can the roller coaster take around the track per mintue?

The answer is 162/9 =18

Step-by-step explanation:

all you really to do is divide then you get your answer.

18

Step-by-step explanation:

162/9 = 18

you have to divide 162 divided by 9 to get 18 which is the number of passengers the roller coaster can take around the track per minute.

answer: 177/8

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)
