A student is studying guppies, a type of fish. The student learns that common guppies normally live in water with temperatures from 22°C to 30°C. The student counts the number of movements in 1 minute at several different
temperatures.

According to the student's graph, about how many movements on average would the guppies most likely make at
30°C?

PLEASE HELP

answer: -1

step-by-step explanation:

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

false
