<span>As of January 8, 2015, the U.S. is $18.1 trillion in debt. (Source: National Priorities Project)
1 Trillion
= 1 Thousand Billion
= 1,000,000,000,000
= 10</span>¹²

---------------------------
U.S National debt currently stands at:
$ 18.1 x 10</span>¹²

*<em>What information would be lost?</em> Well firstly the 0's. The 0's put the size of the number into perspective. The word "trillion" would also be taken out of the picture, once again altering the perspective of the number.
Personally I'd prefer to hear "18.1 Trillion Dollars". Sounds more interesting.</span>
F = Gm1m2/r^2 = 6.67 x 10^-11 * 68.5 * 6.43 x 10^23 / (3.43 x 10^6)^2 = 2.93 x 10^15 / 1.18 x 10^13 = 249.7N
If we subtract the equations we can eliminate the 2 6y's
subtractiong the second from the first:-
10x = 44
x = 4.4
now plug x = 44 into the first equation:-
4*4.4 + 6y = 62
6y = 62 - 4*4.4 = 44.4
y = 44.4/6 = 7.4
the answer is the order pair (4.4,7.4)
The answer would be 2c darling :)
