Answer:
The difference of 8 times a number r and 12 is solved for a number r and is given by 
Step-by-step explanation:
Given problem is the difference of 8 times a number r and 12
It can be written as

To simplify the above expression :
8r-12

( using addition property of equality )

(using division property of equality )

Therefore 
Therefore the difference of 8 times a number r and 12 is solved for a number r and is given by 
It would be 0.4:) hope this helps
Yes it does because it is even in each side
Answer: ∠AOB = 100°
Step-by-step explanation:
This is found in the circle geometry. The theorem in solving this stated that the angle which an arc of a circle subtends at the centre of the circle is twice that which it subtends at any point on the remaining part of the circumference of the circle
Therefore
∠AOB = 2 x ∠ACB
= 2 x 50°
= 100°
