Since the question seems to either miss a variable, or is phrased wrong, I will answer with this. It will take 13 fridays, or 13 weeks for 20 to add up to a number greater than 250.<span />
        
             
        
        
        
The line of the equation perpendicular to y=5 and cuts through (-5,-7) will be given by
m(x-x1)=y-y1
where m=slope.
from y=0x+5, the slope of the perpendicular line m=0,
thus the equation will be:
0(x--5)=y--7
0=y+7
y=-7
The equation is y=-7
        
                    
             
        
        
        
Base times height, and then dives what you got by 2
        
                    
             
        
        
        
Hi There! :)
<span>What 5x23p9x2 and what is the common number?
5</span>×23=115
<span>115</span>×9=1035
<span>1035</span>×2=2070
<span>
Therefore 2070 is the answer
