Answer:
 m = -32.10
Step-by-step explanation:
You solve this the same way you do any two-step linear equation. 
1. Subtract the constant that is on the side of the equal sign with the variable term:
 m/5 = -6.42
2. Multiply by the inverse of the coefficient of the variable. That means multiply by 5 in this case.
 m = 5·(-6.42) = -32.10
_____
Of course, the rules of equality tell you whatever you do to one side of the equation must also be done to the other side. So, when we say subtract 0.12, we mean subtract 0.12 from both sides of the equation. The same for multiplication or division.
 
        
                    
             
        
        
        
D. 7 miles
Step-by-step explanation:
26.5/4 =6.62 
So the best estimate is 7 miles
 
        
             
        
        
        
First, lets note that 

. This leads us with the following problem:

Lets add sin on both sides, and we get:

Now if we divide with sin on both sides we get:

Now we can remember how cot is defined, it is (cos/sin). So we have:

Now take the inverse of cot and we get:

In general we have 

, the reason we have to add pi times n, is because it is a function that has multiple answers, see the picture:
