Find the volume of a pyramid with a square base, where the side length of the base is 19.3\text{ ft}19.3 ft and the height of the pyramid is 16.2\text{ ft}16.2 ft. Round your answer to the nearest tenth of a cubic foot.

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

i would say b) is your answer
