Answer:
B. 110 degrees
Step-by-step explanation:
The measure of an arc equals the measure of its central angle.
4x + 2y = 14
8x + y = 10
7 - 2x = 10 - 8x
7 + 6x = 10
6x = 3
x = 1/2
y = 6
Hope this helps!
Answer: 66
<u>Step-by-step explanation:</u>
20 points per day is the rate, 100 points is the intial amount, and 1420 points is the total.
Use the formula: y = mx + b
- y is the total
- m is the rate
- b is the initial amount
1420 = 20x + 100 <em>plugged the values into the equation</em>
1320 = 20x <em>subtracted 100 from both sides</em>
66 = x <em>divided both sides by 20</em>
