Answer:
4 meters
Step-by-step explanation:
Normally, 100 centimeters should be the normal meter length, but we multiply that by 4 and we get 400 centimeters
 
        
                    
             
        
        
        
713/9
79 2/9       Decimal form: 79.222
713 divided by 9 is 79 with a quotient estimate of 2. 
79 r 2
        
             
        
        
        
50 1/2 <u>divided by</u> 1/4 = 202
A farm was selling 50 1/2 apples to 2 families in need of some food. 1 family got half of what the 2nd family got.
50 1/2 <u>multiplied by</u> 1/4 = 12.625
The first number (50 1/2) is 202 times greater than the second number (1/4)
Hope this helps! :'(
I tried my best. I'm not good at math.
 
        
                    
             
        
        
        
It's called "solve the equation for 'y' ".  That means move things 
around so that you end up with 'y' all alone on one side, and 
everything else on the other side.
You started with                        9x - 7y = -7
Subtract  9x  from each side:        - 7y = -9x - 7
Divide each side by  -7 :                  y = 9/7 x + 1
