To estimate how many miles you are from a thunderstorm, count the seconds between when you see lightning and when you hear thunder.
then divide by 5. write and solve an equation to determine how many seconds s you would count for a thunderstorm that is 2 miles away
the equation is 2 =
n
.
you would count for
seconds.

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

answer: 0.1,0.85
