<span>4x•2-12x=7
Subtract 12x from 4x
-8x*2=7
Divide 2 on both sides
-8x=3.5
Divide both sides by -8
Final Answer: x= -0.4375</span>
Toni can carry up to 5 books
1+2+3b=18

3b=15
divide 3 from both sides
b=5
It takes 2 hours to complete 10
Laps.
48/4 is 12 so it’s it 12 minutes a lap
12x10 is 120 which equals out to 2 hours
Recall your d = rt, distance = rate * time
so... let's say, the plane's speed in still air is "p", and the speed of the wind is "w".
when the plane is travelling with the wind over those 1000 miles, is really not going "p" fast, is going " p + w " fast, since it's going with the wind.
now, when the plane is travelling against the wind, is not going "p" fast either, is going " p - w " fast, since the wind is subtracting speed from it.
bearing in mind he cover the 1000 miles as well as the 880 miles in 2 hrs each way.

what's the speed of the wind? well, 500 - p = w.
Answer:

Step-by-step explanation:
