Step-by-step explanation:
11x=40
X=40/11
There are 7 faces, 12 edges and 24 vertices in a hexagonal pyramid.
You can make 4 out of 18 cubes
Let n be a number of balls: n = 14
In one pan you have 8 balls: 8n
In the other pan you have the rest of balls (14 - 8 = 6) along with a <span>weight of 20 grams = 6n + 20
So the pans are balanced:
8n = 6n + 20
Now, just solve the equation:
8n - 6n = 20
2n = 20
n = 20/2
n = 10
So, you know that a ball weights 10 grams.</span>
