A wrestling tournament begins with 128 competitors. In the first round, each competitor has
1 match against another wrestler. The winner of
each match moves on to the next round until there
is a winner. Write a sequence in which the terms
represent the number of players still in the
tournament at the end of each round. Describe the
sequence? How many rounds are in the
tournament?

do you have the measurements?

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
