4x = 76
Where x is how many awnsers he got correct and 4 how many points each correct question awnsered.
Now you just have to isolate x by dividing both sides of the equation by 4
4x/4 = 76/4
x = 19
So he got 19 questions right and 10 awnsers wrong. In total there were 29 questions on his test

In the case of a 19-side polygon
Hence:
Answer:
Center point:
Radius:
Step-by-step explanation:
The equation of a circle is where is the center point of the circle and is the radius of the circle.
Given our equation , we can see that is and since , our radius is
Therefore, the center point is and the radius is
I believe the answer is B!!
I’m sorry if it’s wrong :(
