Answer: each number represents the sum of the two numbers
Step-by-step explanation:
I’ve never done this question before but bright to sum of the numbers together
 
        
             
        
        
        
To add any fraction You need to make sure that the denominator of the fractions are same. ( denominator in your sum is 19 )
10/19 + 3/19 ( we have the same denominator )
we can also write this problem like
( 10 + 3 ) / 19  { add the numerators together }
13 / 19
So correct option is B.
hope this helped..  :)
        
                    
             
        
        
        
Answer:
12 units
Step-by-step explanation:
Given that :
R(-3,2) 
S(2,2) 
T(2,-5). 
The total length ;
Distance between two points : √[(x2 - x1)² + (y2 - y1)²] 
Distance between R and S :
R = (-3,2) 
S(2,2) 
√[((2 - (-3))^2 + (2 - 2)^2] 
Sqrt(5^2 + 0^2) 
D1 = 5 units 
Distance between S and T:
S(2,2) 
T(2,-5). 
D2 = √[(2 - 2)^2 + (-5 - 2)^2]
D2 = sqrt(0^2 + (-7)^2)
D2 = 7 units 
Hence, total length = D1 + D2 = (5 + 7) = 12 units
