Answer:
41 miles
Step-by-step explanation:
The first week, which is 7 days, Adam walked 2 miles a day. So, we have the multiplication equation: 2 * 7 = 14 miles.
For the next 9 days, Adam walked 3 miles per day. So, we have the multiplication equation: 3 * 9 = 27 miles.
Now, we just add these two values together:
14 + 27 = 41 miles
Thus, the answer is 41 miles.
Hope this helps!
 
        
             
        
        
        
Answer:
r= -1.8
Step-by-step explanation:
Distribute 
-3-18r=14-7
Combine like terms
-3-18r=7
add 3 to both sides
-18r=10
divide by -18
r=-1.8
 
        
             
        
        
        
The answer should be (0, 0).
