Decimal counts 0,1,2,3,4,5,6,7,8,9
Hex counts 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F
Hex "D" is = to Decimal 13
Hex "7" is = to Decimal 07
Thus Hex "D" + Hex "7" = Hex "14" or to Decimal 20
D7 = 11010111
If: d+7 = 5 Then: d = -2 by subtracting 7 from both sides
Expressed as a sum in hexadecimal form, F + D = 1C.
D
(d+7)/(d2-49)(d+7)/(d+7)(d-7)1/(d-7)
D = 13
d2 + 8d + 7 = (d + 7) (d + 1)

Doc, Happy, Grumpy, Sleepy, Bashful, Sneezy and Dopey equal[s] the 7 dwarves.
The answer is 5B because d is 13 and 13 times 7 is 91, and 16 goes into 91 5 times remainder 11, and 11 is B, so it is 5B
what is d over 12 plus 7 times d over 12 equal
