D) a = 24, c = 48, e = 22, i = 80 is the correct answer.
hope this helps!
        
                    
             
        
        
        
Hi there! 
In order to find the value of N, we'll need to set the value of the angle containing the variable n equal to 90. This is because in perpendicular lines, all angles are equal to 90.
WORK: 
5n - 25 = 90 
5n = 115 
n = 23
        
             
        
        
        
Answer:
Single Solution of 3.2 (16/5)
Step-by-step explanation:
3x = 8x -16 <--- I combine like terms.
-5x = -16 
-16/-5 = x 
x = 3.2
BTW Negative times a Negative equals a positive.
 
        
             
        
        
        
Answer:
whatever% of anything, is just (whatever/100) * anything.
there were a total of 560000 votes, now, off those some are valid and some are invalid.
we know 15% of that are invalid, that simply means that 85% are valid, since 85% + 15% is the whole thing, or 100%, if 15% are not good, the other 85% are the good ones.
how many are the valid ones anyway?  well, 85% of 560000, which is just (85/100) * 560000.
we know that off those valid ones, the candidate got 75% of those, so how much is 75% of that?
well, (75/100) * [ (85/100) * 560000 ].
