Answer:
Yes you are correct.
Step-by-step explanation:
The best way to check theese types of questions is go back in plug in X with your answer so 88+97+80+90(which is x)=360 then divide by 4 and get 90! So yes you are correct good job!
First solve one of the two equations (whichever is easier) for either x or y, whichever variable is easier. Let's say you solved for x. Then plug what x equals into the 2nd equation as x. So if you got x = 2y + 1, plug that into your other equation and solve for y (you should get a number value).
Now take whatever y equals and plug that back into what you got when you solved for x (the x = 2y + 1) to get what x equals.
I think c. 8 hope this helps
If you round (to the hundreths), it would be 97/100
Without rounding, it is 96/100 which simplifies to 24/25
(a).ABO is equivalent to x because they are base angles of an isosceles triangle (because the radii are equal). The same applies for CBO being equivalent to y
(b). Since angle COA is 180°, ABC is equivalent to half of COA which is 90°
