2x + 50 = 100
Step-by-step explanation:
twice a number would be represented as 2x. And 50ore than that would be + 50. And since it equals 100 it would be = 100.
Answer: 1
B is the center of a circle of radius 1. A and C are on the circle 100 degrees apart. So arc AC is 100 degrees. Arc AC the long way around is 360-100=260 degrees. That means any point D on arc AC will subtend a 130 degree angle. BD is a radius for all of those, and the radius is 1.
