Answer:
15 < n < 25
Step-by-step explanation:
According to the triangle inequality theorem, any two sides lengths' sum should be greater than the third side. This also implies that to find the <em>possible length of the 3rd side given other two sides (let two given sides be x and y)</em>, we can say that the 3rd side length will be between x+y and x-y.
Hence, we can say that <em><u>n should be between 20+5 and 20-5</u></em>.
So, 20 - 5 < n < 20 + 5, which is
15 < n < 25
<em>This is the correct answer.</em>
Answer:
2.75 miles jogged on the fourth day
Step-by-step explanation:
Justin jogged 2 miles on the first day.
On the second day he jogged 75% of 2 miles. To find 75% of 2 miles we need to divide by 100 and multiply by 75.
2 / 100 = 0.02 x 75 = 1.5 miles jogged on the second day. (3.5 miles jogged in total so far)
On the third day he jogged 1.5 miles more than the last day:
1.5 + 1.5 = 3 (6.5 miles jogged so far)
9.25 total miles were jogged, meaning that we will need to subtract 6.5 from 9.25 to get the answer:
9.25 - 6.5 = 2.75 miles jogged on the fourth day
