Answer:
25/2
Step-by-step explanation:
The marked angles are supplementary, so ...
117 + (6x -12) = 180
6x = 75 . . . . . . . . . . . subtract 105
x = 25/2 . . . . . . . . . . divide by 6
Answer:
The answer is d (-21/2 , 2)

Let their ages be g and k. Then g = k + 3.
Next: (g+7) + (k+7) = 41.
Substituting k + 3 for g in the above equation, we get k + 3 + 7 + k + 7 = 41.
Combining like terms: 2k + 17 = 41. Then 2k = 24, and k = 12.
