<span>All the gold ever mined would fit into a single cube about 60 feet on a side.
</span>
A figure that is widely used by investors comes from Thomson Reuters GFMS, which produces an annual gold survey.
Their
latest figure for all the gold in the world is 171,300 tonnes.
A cube made of 171,300 tonnes would be about
20.7m (68ft) on each side.
Answer: x = -4
Step-by-step explanation:
1/2 * (x - (-6)) = 1
distribute
1/2x + 3 = 1
isolate the variable
1/2x = -2
x = - 4
The variation from x to y is an illustration of a direct variation
The value of x when y = 2 is -19/7
<h3>How to determine the value of x?</h3>
The variation is a direct variation.
So, we have:
x = ky
Where k represents the constant of variation
Make k the subject
k = x/y
This gives
x1/y1 = x2/y2
So, we have:
-19/14 = x/2
Multiply both sides by 2
x = -19/14 * 2
Evaluate
x = -19/7
Hence, the value of x when y = 2 is -19/7
