Knowing how to write two-column geometry proofs provides a solid basis for working with theorems. Practicing these strategies will help you write geometry proofs easily in no time:
Make a game plan. Try to figure out how to get from the givens to the prove conclusion with a plain English, commonsense argument before you worry about how to write the formal, two-column proof.
Look up how to do geometry proofs and the first thing that should pop up if your on google should be a site called dummies.com
        
             
        
        
        
Answer:
135
Step-by-step explanation:
simply You're asked 15% of 900 so
900 x 15/100 =135
 
        
             
        
        
        
Answer: The starting time is 2:27 and finishing time is 7:09.     
Step-by-step explanation: It is given that Ben started from 4th street and he finished at 98th street. 
Also, at 3:00, he was on 15th street and at 4:30, he was on 45th street.
That is, time taken to cover (45-15), i.e., 30 streets is 90 minutes,                           so the time taken to cover 1 street is 3 minutes.
Therefore, Ben covers distance from one street to second in 3 minutes. Since he started from 4th street, and there are 11 streets to cover between 4 and 15, so Ben's starting time was (3:00 - 3×11 min) = 2:27.
And his finishing time was (4:30 + 3×53 min) = 7:09.
Again, the equation that tells us on what street 'N' he was after time 'T' of his starting can be written as 

Thus, the starting and finishing time was 2:27 and 7:09 respectively.
 
        
             
        
        
        
3 + 8 + 10 + 12 + 15 = 48
48 / 5 = 9.6 or 10
3 - 7
8 - 2
10 - 0
12 - 2
15 - 5
7 + 2 + 0 + 2 + 5 = 16
16 / 5 = 3.2 or 3
