Questions Ray has a backyard in the shape of a square with a semi circle on top. The square part of the yard has sides that are 20 feet long. How many square feet is Ray's backyard? A 557 square feet B 714 square feet C 1.028 square feet D 1.656 square feet​

x/3-10=8

x/3=18

x=48

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

the answer is 15.50 for one mile

b) is slope: 0   y- intercept 15.5
