Let x be the number so that the equation is:
$$x−15=7$$
Solve for x. Add 15 to both sides:
$$x−15+15=7+15$$
$$x=22$$
So, the number is 22.

A skier wears a jacket filled with goose down that is 15mmthick. Another skier wears a wool sweater that is 5.0mmthick. Both have the same surface area. Assuming thetemperature difference between the inner and outer surfaces of eachgarment is the same, calculate the ratio (wool./goose down) of theheat lost due to conduction during the same time interval.

Airlines schedule about 5.5 hours of flying time for an A320 Airbus to fly from Dulles International Airport near Washington, D.C., to Los Angeles International Airport. Airlines schedule about 4.5 hours of flying time for the reverse direction. The distance between these airports is about 2,300 miles. They allow about 0.4 hour for takeoff and landing.
a. From this information, estimate (to the nearest 5 mph) the average wind speed the airlines assume in making their schedule.
b. What average airplane speed (to the nearest 5 mph) do the airlines assume in making their schedule?
