A club's first meeting was attended by 21 people. The second meeting was attended by 3 times as many people as the first meeting. How many people attended the second meeting? anwser:

step by step example

63 people

Step-by-step explanation:

first meeting 21 people

second meeting 3 time as many people as first meeting

so 21 ×3=63

i just try it..

twenty one multiplied by three to get sixty three which is the answer

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)

so, converting firstly the mixed fractions to improper fractions and then "adding".
