First, combine like terms to get 4n-7=5n+1
add 7 to both sides to get 4n=5n+8
subtract 5n from both sides to get -n=8
multiply both sides by -1 to get an answer of n=-8
= 9 * 10^5 * 3 * 10^10
= 27 * 10^5 * 10^10
= 27 * 10^15
= 2.7 * 10^16 - The best selection appears to be the first option.
Good luck :)
If you would like to know what is 9 divided by 3/4, you can calculate this using the following steps:
9 / 3/4 = 9 * 4/3 = 12
The correct result would be 12.
