Answer:
x = -5
Step-by-step explanation:
4-2(x+7)=3(x+5)
Distribute
4 -2x-14 = 3x+15
Combine like terms
-2x-10 = 3x+15
Add 2x to each side
-2x-10+2x= 3x+15+2x
-10 = 5x+15
Subtract 15 from each side
-10-15 = 5x+15
-25 = 5x
Divide by 5
-25/5 = 5x/5
-5 =x

Let the time to hike up the hill = t
As given that the total time time up and down is 3 hrs, therefore
The time down the hill = 3-t
The distance up and down is the same.
Distance = speed * time
t=1.8
Hence, time taken to uphill = 1.8 hours
Time taken to down hill = 3-18 = 1.2 hours
Answer:
42 ft
Step-by-step explanation:
14 times 14=196
R of circle =7
7 squared=49
49 times pi= 153.938040026
196-153.938040026= 42.0619599741
Rounded to 1 decimal=42.1
Rounded to whole number = 42

Answer:
- Age (decreasing): Jason, Tim, Michael, Nick
- Height: (decreasing): Tim, Michael, Nick, Jason
- Weight: (decreasing): Nick, Jason, Tim, Michael
Step-by-step explanation:
The given tallest, oldest, lightest, and heaviest are easy to fill in.
Michael is already 4th in weight, so cannot be 1st or 4th in age. If Tim is older, then the age rank must be Jason, Tim, Michael, Nick.
Michael cannot be 1st, 3rd, or 4th in height, so must be second. If Jason is shorter than Nick, then the 3rd and 4th in height must be Nick and Jason.
The only remaining possibilities for weight are that Tim is 3rd (cannot be 2nd), so Jason is 2nd.
