Iwill give bralienst john starts on the ground floor of a building. he runs up five flights of stairs, then runs up 6 flights of stairs, then runs down 8 flights of stairs, then runs up four flights of stairs, and then stops. each story of the building is 11 feet high. how many feet above the ground is john when he stops?

The answer is 77. I know because I have had the question before too.

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
