DOC = 70
BOC = 110
AOD = 110
Step-by-step explanation:
AOB is supplementary to BOC and AOD, which means together they equal 180. 180-70=110, so BOC and AOD are both 110.
AOB and DOC are vertical angles to each other, so are AOD and BOC. Vertical angles are always equal to each other. So since AOB is 70, so is DOC.
Hope this makes sense:)
Answer:

Step-by-step explanation:
I am going to say that:
Mary's amount is x.
Ashley's amount is y.

3 times this amount is 3(y + z).
At least 3 times means that z is equal or greater than 3(y + z).
So
