Home is 0.6 miles away from the store
How to solve such time related questions? 
The key concept for solving such questions is the relationship between speed, distance and time.
The relationship between them is Distance = Speed x Time
Given:-
Total time taken by girl to complete the trip = 15 minutes =  hours
 hours
Speed while riding going = 6 miles per hour
Speed while coming back = 4 miles per hour
 
 Total time taken by girl  = 
Time taken while going +   Time taken while coming back      - (1)
   Let x be distance from home to store
         =  Time taken while going
 =  Time taken while going
  = Time taken while coming back
 = Time taken while coming back
     Substituting in (1) we get
       
       
        
       
      x = 0.6 miles
Thus home is 0.6 miles away from the store

Step-by-step explanation:
first you have to solve for x 
35x - 5=50
35-35x-5= 50-35
x-5=15
x- 5÷5=15÷5
x=3
Now we have to substitute x into the equation.
35×(3)-5=
175-5=170
angle UVW= 170 
to find angle HUW instead of solving the equation just subtract 170 from 50 and you will get 120.
angle UVH=50
angle HUW=120
angle UVW=170

Problem 11
<h3>Answer:  h = 
2A/b</h3>
------------------
Explanation:
We need to get h by itself. To do so, we first multiply both sides by 2. Then we divide both sides by b
A = (1/2)*b*h
2A = b*h
b*h = 2A
h = 2A/b
================================================
Problem 12
<h3>Answers:</h3>
- Equation:   (n+2)/5 = 14
- Solution to that equation:  n = 68
------------------
Explanation:
The number n is increased by 2 to get n+2
Then we divide by 5 to get (n+2)/5
This is set equal to 14 to get the equation (n+2)/5 = 14
Solving the equation would look like this
(n+2)/5 = 14
n+2 = 5*14 .... multiply both sides by 5
n+2 = 70
n = 70-2 .... subtract 2 from both sides
n = 68
================================================
Problem 13
<h3>Answer: Not a solution</h3>
------------------
Explanation:
We'll replace every copy of x with -3 and simplify
-2x + 5 > 13
-2*(-3) + 5 > 13
6 + 5 > 13
11 > 13
The last inequality is false because 11 is not greater than 13. Since the last inequality is false, this makes the first inequality false when x = -3.
Therefore, x = -3 is not a solution.
 
        
             
        
        
        
Convert 20 min to hrs: 20/60 = 1/3 hr
Let t = time on the bikethent-(1/3) = time on the bus
Write a dist equation Dist = speed * time:Bike dist + bus dist = 26 mi6t + 30[t-(1/3)] = 26:6t + 30t - 10 = 2636t = 26 + 1036t = 36t = 1 hr on the bike
6 mph for 1 h = 6 mi from house to the bus station
Check solution by finding the distance6(1) + 30(2/3) =6 + 20 = 26 mi
