HEL One number is 6 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 660, find the numbers.

70, 420, 170

Step-by-step explanation:

x+6x+x+100 = 660

8x+100=660

8x=660-100

x=560/8=70

1; 35 is the ratio

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)
