21.9089 is the geometric mean..
4x - 1/3 = 7/1
+1/3 +1/3
_______________
4x = 7.3 (repeating)
(divide each side by 4)
x = 7.3 (repeating) / 4
Not sure why, but I wasn't able to post my solution as text, so I've written it elsewhere and am posting screenshots of it here.
In the fifth attachment, the first solution is shown above the second one.
Each Cm is equal to 10.5 kilometers
Hey!

Find the amount of points each student earned!
Erika: 100 x 0.84 = 84 points earned out of 100.
Joe: 100 / 6 = 16.6667... x 5 = 83.333... = 83.3 points earned out of 100.
Malcolm: √7225 = 85 points earned out of 100.
Stephanie: 83/100 = 83 points earned out of 100.
--------------------------------------------------
Plot the points of each student on the number line you were given!

Hope This Helped! Good Luck!
