Answer:</h2>
The equation that will be used to find t is:

<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:

Hence, distance traveled in first part of hike is:

- 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:

Hence, time spent by him in second part of hike is:

Answer:
$450
Step-by-step explanation:
Let R be the hourly pay rate in dollars per hour. Hannah worked 10 hours and Zach worked 9 hours for a total of $950, so we get the equation:
10R + 9R = 950
Solve for R:
19R = 950
R = 50
Zach worked for 9 hours, so the total he earned is:
9 hours * 50 dollars/hour = $450
4 x 365 = 1460 cents per year. 14.60
Answer:
C (4,7,10)
Step-by-step explanation:
For a set of numbers to represent the lengths of sides of triangle:
Sum of any two numbers must always be greater than than the third side.
out of the give options only C (4,7,10) follows the above condition.
