Answer:
All I see is white need to post another
Yes, good job! Since AB and CD are congruent, so are the angles

Answer:</h2>
The equation that will be used to find t is:
![3(2-t)+1.5t=5](https://tex.z-dn.net/?f=3%282-t%29%2B1.5t%3D5)
<h2>
Step-by-step explanation:</h2>
Total distance that is traveled by Amir is: 5 miles.
and the total time taken by him is: 2 hours.
On the first part of the hike, Amir averaged 3 miles per hour.
Let t denote the time he spent hiking during the second i.e. difficult part of the hike.
- Hence, the time he spent in first part of hike is: 2-t
( Since, the total time was 2 hours)
Also, we know that:
![Distance=Speed\times Time](https://tex.z-dn.net/?f=Distance%3DSpeed%5Ctimes%20Time)
Hence, distance traveled in first part of hike is:
![Distance=3\times (2-t)](https://tex.z-dn.net/?f=Distance%3D3%5Ctimes%20%282-t%29)
- Now, the distance he will travel in second part of hike will be: 5-3(2-t)
Since the total distance traveled by him is 5 miles.
It is given that his speed decreased to 1.5 miles per hour.
Now, we know that:
![Time=\dfrac{Distance}{Speed}](https://tex.z-dn.net/?f=Time%3D%5Cdfrac%7BDistance%7D%7BSpeed%7D)
Hence, time spent by him in second part of hike is:
![t=\dfrac{5-3(2-t)}{1.5}\\\\i.e.\\\\1.5t=5-3(2-t)\\\\i.e.\\\\3(2-t)+1.5t=5](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7B5-3%282-t%29%7D%7B1.5%7D%5C%5C%5C%5Ci.e.%5C%5C%5C%5C1.5t%3D5-3%282-t%29%5C%5C%5C%5Ci.e.%5C%5C%5C%5C3%282-t%29%2B1.5t%3D5)
All numbers that only have one and itself as factors are prime. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
