Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation. 2. If y varies inversely as x, and y=2/5 when x=2, find y when x= 1

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

hi there!

the answer will be d: 2

there are infinitely many solutions.

combine all like terms then its just a 2 step equation
