x = 8
Explanation:
f(x) = g(x)
Given:
f(x) = -20x + 11g(x) = -19x + 3solve:
-20x + 11 = -19x + 3
-20x + 19x = 3 - 11
-x = -8
x = 8
Ответ:
3
Step-by-step explanation:
For this question, you need to make change the denominators of the fractions to be equal, making them the same lowest common denominator.
8/9 -> 40/45
4/15 -> 12/45
Since 12 goes into 40 3 1/3 times, he can patrol that many neighborhoods in 8/9's of an hour, which is rounded to 3 because he doesn't have enough time for 4.
