Lauren dove into a swimming pool from a 15 foot high diving board with an initial upward velocity of 8 feet per second find the time it took one to enter the water use the equation h=-16t^2 + vt + s, where h is height in feet, t is time in seconds, v is the initial upward velocity in feet per second, and s is the initial height in feet.

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

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
