Answer:
Answer choice 'A'
Step-by-step explanation:
since the rightmost angle is 63°, then, the one across it has to equal 63°.
then y=40°. the only answer choice that would be correct would be 'A', but if you want to double check, a line has to equal 180°.
. So, then . So both parts of the answer choice are right
Since there are 48 paintings being donated by 12 collectors, then we can say that each collector will donate 4 paintings.
This means that Sergio will have 4 less paintings then he had before, which was represented by . Thus, our expression is now .
The number of paintings Sergio will have in his art collection after his donation is p - 4
Given:
Number of Sergio's paintings = p
Total number of paintings to donate = 48
Number of collectors to donate (including Sergio) = 12
Number of paintings donated by each collector = Total number of paintings to donate ÷ Number of collectors to donate
= 48 ÷ 12
= 4 paintings per collector
Therefore,
Number of paintings Sergio will have in his art collection after his donation = Number of Sergio's paintings - Number of paintings donated by each collector
= p - 4
