Answer:
No. Hank wont be able to complete the hike.
Step-by-step explanation:
Time Available for hike = 4 hours
The expression which represents the time Hank needs to complete the hike is:
d is the distance in miles of the hiking trail. Since, Hank would like to hike 6 miles, d = 6
e is the elevation gain in thousands. Since, the trail hank will hike on has an elevation gain of 3000, so e = 3
Using these values in the expression, we get:
This means Hank should allow him 4.5 hours or the hike. Since he has only 4 hours available, he wont be able to complete the hike. So the answer to this question is No.
<u>Answer</u>:
Therefore has one solution.
<u>explanation</u>:
Given equations:
6x + y = -7
-24x -7y = 25
Make y the subject:
6x + y = -7
y = -7 - 6x ..............equation 1
-24x -7y = 25
-7y = 25 + 24x
y = (25 + 24x)/-7 ..........equation 2
Solve them simultaneously:
(25 + 24x)/-7 = -7 - 6x
25 + 24x = -7 (-7 - 6x)
25 + 24x = 49 + 42x
42x - 24x = 25- 42
18x = -24
x =
Then y is:
y = -7 - 6x
y = -7 - 6( )
y = 1
Has one separate value of x and y: ( , 1 ); so it has one solution.
