Answer:
5 x (4+y)
Step-by-step explanation:
 
        
             
        
        
        
-9(3-r)=45
-27+9t=45
9r=45+27
R=72/9
R=8 
The answer is 8 not -8
        
             
        
        
        
Answer:
$103.6 left
Step-by-step explanation:
First, multiply the amount she earns an hour times how many hours she worked:
9.25 x 14 = 129.5
Then divide the total by 1/5:
129.5 / 5 = 25.9
Then subtract that value from the total:
129.5 - 25.9 = 103.6
$103.6 is your answer
Hope this helps!
 
        
                    
             
        
        
        
Using the Sine Rule:-
20 /sin 45 =  BC / sin 30
BC = 20 sin 30 / sin45
  = 20 * 1/2  /  1 / sqrt2
  = 20 * 1/2 * sqrt2
=  10 sqrt2   answer
        
             
        
        
        
The table containing the data needed for this problem is attached on this answer. This data is used to determine the best fit line that is extracted from this multitude of points given. Best fit line is described as a line in which the variation of each point to the line is the minimum. We plot the data using MS Excel and is shown in the figure attached as well. We determine the trendline of the graph by the function in MS Excel. The equation of the trendline is expressed as <span>y = -26.059x + 722.63 in which the coefficient of determination, r^2 = 0.8947. </span>
