Question

I can imagine you notice that the air temperature dropped 10 degrees every 1000 meters increase in elevation write a multiplication expression to represent the decrease in temperature if you hike up the mountain 3000 meters

Answer 1

this is your expression

x / 1000 * -10

so x is the amount hiked so in this situation x = 3000

3000/1000 * -10

3 * -10

-30 degrees

the temperature wouldve dropped 30 degrees
