To answer this item, we let x be the number that is not unknown in this item such that the situation in this problem can be expressed as follows,
x - 9.3 = 68.91
Adding 9.3 to both sides of the equation,
x - 9.3 + 9.3 = 68.91 + 9.3
Simplifying,
x = 78.21
The answer to this item is 78.21, this I think is the first choice except that it is mistakenly written as 7.21 only.

Well think about the size of our world. Its pretty big and it would be really hard to map something out the size of the world. Using a scale like this 1:1000 because it shows 1 for every 1000 miles or kilometers. Or even greater units of measurement, less spaced and yet still an accurate representation. If put through the backed scaled equation, you would get the actual size jsut by multiplying the number in this case 1 or more by 1000 and you’d get the exact measurements.
