You cannot memorize a whole multiplication chart in one day, but if you go online and search multiplication stories, there may be some stories to help you memorize your facts quicker depending on your learning style. Also try and remember that any number times any number is just that number being added over and over again a certain amount of times. For example: 3*4= 3+3+3+3 Hope this helps :)
        
             
        
        
        
Answer:
70.0000000001 meters per second
Step-by-step explanation:
The formula is to multiply by the factor 0.27777777777817.
252 km/h * 0.27777777777817 = 70.0000000001
 
        
             
        
        
        
Your answer would be x = 12.41 
6.15 (x - 8.86) = 21.83
      *6.15 * 6.15
6.15x - 54.49 = 21.83
         + 54.49  + 54.49
6.15x = 76.32
/6.15    /6.15
x = 12.41
        
             
        
        
        
Y=MX+B
M = slope
B = y intercept (number that intersects with the line in the y axis)
y=-3/4x+2
It starts on the y intercept (2) then we travel to the next point (4 on the x axis)
So we travel 3 spaces down (-3) landing on the origin (0,0) then four spaces to the right (4). Getting the slope of -3/4 (rise over run)
Then just plug in these into the equation 
y = -3/4 + 2
