To determine the value of 'x', the masses of the rocks collected by Emily and Ashli need to be clearly defined. The mean mass of Ashli's rocks is 0.2 kilograms greater than that of Emily's, but the specific masses are not provided. Without knowing the individual masses or the total mass of either collection, calculating 'x' is impossible. Additional data regarding the rocks' weights is essential for solving the problem. Clarifying this missing information is crucial for finding the value of 'x'.

Emily and Ashli each collected six rocks, and the masses of the rocks
are shown in the table below. The mean of the masses of the rocks
Ashli collected is 0.2 kilogram greater than the mean of the masses
of the rocks Emily collected. What is the value of ‘x’ ?

I have moved your post to its own thread, as this is a better fit than in an announcement regarding the anniversary of our founding. ;)

It seems some information is missing...
 

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
