There is not really much to "solve". I suppose you mean 1.3 x 10-12. This is scientific notation, a convenient way to write very large or very small numbers. To change this into standard notation, move the decimal point in 1.3 12 positions to the left (adding digits if necessary). For a positive exponent, move the decimal point to the right. Thus, 1.3 x 10-12 = 0.0000000000013. However, it is better to learn about scientific notation, and just keep such large or small numbers in scientific notation, since that is much easier to read.
x=13
5.0009 x 1012 = 5,000,900,000,000
To solve for x, we'd have to know what this expression equals.
You divide the number of miles by six trillion (6 x 1012).You divide the number of miles by six trillion (6 x 1012).You divide the number of miles by six trillion (6 x 1012).You divide the number of miles by six trillion (6 x 1012).
0.09 x 1012
x - 13 = 5 x = 18
x=13
5.0009 x 1012 = 5,000,900,000,000
To solve for x, we'd have to know what this expression equals.
X +13 equals 22, X equals nine
x-29 = 13+2x x-2x = 13+29 -x = 42 x = -42
You divide the number of miles by six trillion (6 x 1012).You divide the number of miles by six trillion (6 x 1012).You divide the number of miles by six trillion (6 x 1012).You divide the number of miles by six trillion (6 x 1012).
0.09 x 1012
-9-2x+x = -13 -2x+x = -13+9 -x = -4 x = 4
Set up the equation and solve: x + 5 = -13 (next subtract 5 from each side of the equation to solve for x) x = -18
x-9y
542 X 13 = 7046
