Answer:
She rode her bike 21 miles
6/x = 18/27
cross multiply
18x = 6*27
18x = 162
divide both sides by 18
x = 9
(6,2) is not a solution to the system. It doesn't satisfy either inequality. (The sum is exactly 8, not "more than 8".)
Each time, the number is divided by 3.
99/3=33
33/3=11
11/3= 3 2/3
Divide the last number by 3 to get the next number.
Divide fractions by multiplying by the reciprocal of the second number.
11/3*1/3= 11/9
11/9= 1 2/9
Final answer: 1 2/9
Also can be written as 11/9 (Improper fraction)
