Alright here's the breakdown:
your trying to find how many miles per day 
so
 take the miles (290) and the days it took (5) 
and 
divide the miles by the days it took (290/5) 
and the answer is 
58 mi. per day
        
                    
             
        
        
        
<u>Answer:</u>
None
<u>Explanation:</u>
-3(2+7) = -3×9 = -27
-6+21 = 15
-21+6 = -15
Hence there is no equivalence
 
        
             
        
        
        
Math answers to fraction 2356 divided by 27 can be calculated as follows.
2356/27 math problems division = 87.2592592593. Therefore 87.2592592593 to 2 decimal places= 87.26
2356/27 divided by 2 » (2356/27) ÷ 2 » 87.2592592593 ÷ 2 = 43.6296296296 .
        
             
        
        
        
Given:
Four equations in the options.
To find:
The equation which represents a proportional relationship.
Solution:
If y is proportional to x, then


where, k is the constant of proportionality.
In this case if x=0, then y=0. It means the graph of a proportional relationship passes through the origin.
From the given options, only option B, i.e.,  , is of the
, is of the  , where,
, where,  .
.
So, the equation  represents a proportional relationship.
 represents a proportional relationship.
Therefore, the correct option is B.
 
        
             
        
        
        
Since one side is 40°, you subtract that from 180.
180° - 40°= 140°.
So therefore your missing side lengths are 140, 40, and 140.
hopefully this helps
