Answer:
x=16 and y=9
Step-by-step explanation:
2y+30=3y+21[Diagonals of parallelogram are equal]
30-21=3y-2y
y=9
3y=2x-5[Diagonals of parallelogram are equal]
3×9=2x-5
27=2x-5
2x=27+5
x=32/2=16

Answer: B and F
Step-by-step explanation:
Since, In the first case original amount = 45
So, the increasing percentage when the original amount increases to 75,
=   %
 %
In second case original amount = 75
So the decreasing percentage when the original amount decreases to 45,
=     %
 %
Thus, We found that the ratio of the percent increase is not the same as the percent decrease ( because,    
 
Also, The original amount of the present increase is different from the original amount for the persons decrease. ( Because,  
 
Therefore, Option B and F is correct only.

Answer:
   arithmetic; common difference of 5
Step-by-step explanation:
It usually works well to check differences first. Here, they are ...
   8 -3 = 5
   13 -8 = 5
These are the same value, so the sequence is arithmetic with a common difference of 5.
