The rectangle OABC has one vertex at O, the center of the circle. A second vertex A is 3cm from the edge of the circle as shown below. The vertex A is also a distance of 15cm from C. (a). what is the radius of the circle? (b). Find the length of AB, correct to 1 decimal place.​

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
