Answer:
D
Step-by-step explanation:
usually anything with 11 on the numerator is a repeating decimal and the 0.37 is closest to 36. 
so by guessing you know is D
 
        
                    
             
        
        
        
4) You know slope-intercept form is y=mx+b. So using these two given points, you can find the slope! 
(-8,5)  (-3,10) [Use the y1-y2 over x1-x2 formula to solve for slope]
10 - 5         5
---------   = ----- = 1 
-3-(-8)         5
Hurray! You got a slope of one. Now substitute this back into your original equation:
y=mx+b --> y=1x+b 
Next, we find what our "b" is, or what our y-intercept is:
Using one of the previous points given, substitute them into the new equation:
[I used the point (-3, 10) ]
y=1x+b
10=1(-3)+b  SUBSTITUTE 
10=-3+b     MULTIPLY
10=-3+b
+3   +3    ADD
----------
13=b     SIMPLIFY 
So, now we have our y-intercept. Use this and plug it into the equation:
y=1x+b --> y=1x+13 
y=1x+13 is our final answer.
5) So for perpendicular lines, your slope will be the opposite reciprocal of the original slope. (Ex: Slope is 2, but perpendicular slope is -1/2) 
We have the equation y= 3x-1, so find the reciprocal slope! 
--> y=-1/3x-1 
Good! Now we take our given point, (9, -4) and plug it into the new equation:
y=-1/3x-1
-4=-1/3(9)+b   SUBSTITUTE and revert "-1" to "b", for we are trying to find the y-     -4=-3+b          intercept of our perpendicular equation. 
+3   +3            ADD
--------
-1=b    SIMPLIFY 
So, our final answer is y=-1/3x+(-1)
6) I don't know, sorry! :( 
        
             
        
        
        

Distribute 5 using the Distributive Property:
5(x+24)
Multiply 5 by x:
5x
Multiply 5 by 24:
120
Now, add the products:
5x+120 (Answer)
Hope it helps! Enjoy your day :)

Answer:
7.2 km
Step-by-step explanation:
Given that:
Hours taken = 2 hours
Walk rate = 1 m/s
Distance = Speed * time 
Time taken in seconds = 2 * 60 * 60 = 7200 s
Hence, 
Distance = 1 m/s * 7200s 
Distance = 7200 meters 
Distance in km = 7200 / 1000 = 7.2 km
