Answer:
Step-by-step explanation:
15n - 45/5 = 6n - 9...reduce any fractions
15n - 9 = 6n - 9 ...subtract 6n from both sides
15n -9 - 6n = 6n - 6n - 9...combine terms
9n - 9 = -9....add 9 to both sides
9n - 9 + 9 = -9 + 9...combine terms
9n = 0....divide both sides by 9
n = 0/9 which = 0

Answer:
5.2
Step-by-step explanation:
distance(Mercury, Sun) = 5.8 x 10^7
distance(Venus, Sun) = 1.1 x 10^8
distance(Venus, Mars) = 1.1 x 10^8 - 5.8 x 10^7
The subtraction is a little easier if you borrow a power of 10 from the 10^8, multiplying 1.1 by 10.
simply subtract 5.8 from 11.0.
This gives us a result of 5.2 x 10^7.
