A plane flies over city A and reaches city B in 12 minutes, which is 120 miles away from it. Find the speed of the plane in miles per hour assuming the plane flew at a constant speed.

Which system of linear inequalities is represented by the graph?

Someone answer asap for ! the boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a. e = 2b - 212 b. b = 2e - 212 c. e = -2b + 212 d. b = -2e + 212

Xy x xy if a and b are positive integers such that a*b=9 and b*a=72 what is the value of a/b
