Directions - if y varies directly with x, write an equation for the direct variation . then find the value. questions - 1-if y =-4 when x =10, find y when x=5 2. if y =12 when x =-15, find y when x =2. 3-find x when y=18, if y=9 when x =8. hurry i need answers now

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
