Click For Summary
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 'Area of Overlapping Squares'

Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
