Answer:
1/2 = 0.5 / 1/2 of 100 is 50
Step-by-step explanation:
I am not sure what you are trying to say here but I will tell you what I know:
1/2 is equal to 0.5
So 50 x 1/2 = 25  
And 50 x 0.5 = 25
So 100 x 0.5 = 50
 
        
             
        
        
        
You subtract the length of the Lupu Bridge by the length of thee Hart Bridge after you round them to the nearest thousandth and you get your final answer!
 12,795 -> 13,000
   3,845 -> 4,000
 13,000 - 4,000 = your answer
        
             
        
        
        
Answer:
Enter the equations.
Multiply each equation by a number to get the lowest common multiple for one of the variables.
Add or subtract the two equations to eliminate that variable .
Substitute that variable into one of the equations and solve for the other variable.
 
        
             
        
        
        
Answer:  35
Step-by-step explanation:
Given : A bag contains four red marbles, two green ones, one lavender one, three yellows, and one orange marble. 
Total = 4+2+1+3+1=11
To find sets of four marbles include none of the red ones, we need to exclude red marbles when we count the total number of marbles.
Then, the total marbles(exclude red) =11-4=7
Now, the combination of 7 marbles taking 4 at a time is given by :-
 
Hence, the number of sets of four marbles include none of the red ones = 35
