1 answer:

5 0

The three points are on the same line, so the slopes formed by any of the two points stay the same
[-7-(-5)]/(-1-0)=[n-(-5)/(1-0)
(n+5)=2
n=-3

log_{x+5} 36 = 2\\\\
\Longrightarrow~~(x+5)^2 = 36\\\\
(x+5)^2 = 6^2\\\\
x+5= 6\\\\
x = 6 - 5 = \boxed{\bold{1}}$

Answer:

3.61 miles

Step-by-step explanation:

Given that:

Length of track = 5/6 of a mile

Number times Mary was able to run around the track = 4 1/3 times

Total miles ran by Mary :

(Equivalent mile of the track * number of times Mary ran around the track)

5/6 of a mile * 4 1/3 times

5/6 * 13/3

= 65 / 18

= 3.611111 miles

Hence, total Number of miles ran by Mary is 3.61 miles
