➢ Calculate the distance and displacement in each of the following situations. Include a direction (example: north or northwest) with your answer. David walks 3 km north, and then turns east and walks 4 km.

Amy runs 2 miles south, then turns around and runs 3 miles north.

Derrick crawls 4 feet south, and then turns east and crawls 6 feet.

Ray runs 30 feet north, 30 feet west, and then 30 feet south.

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
