90=7.68x+66.96
subtract the 66.96 from the 90
then just divide
Answer:
V=390mph and W=30mph
Step-by-step explanation:
Let V be the speed of the airplane and W the speed of the wind.
We have two travels and the formula v=d/t:
V+W=630miles/1.5hr (With the wind)
V-W=630miles/1.75hr (agains the wind)
Clear V from the 1st equation. V=(630/1.5)-W
And replace it into the 2nd equation:
(630/1.5)-W-W=630/1.75
420-2W=360
420-360=2W
W = 60/2
W = 30mi/hr is the wind speed.
Now, we can find V using one equation:
V=(630/1.75)+30 = 360+30
V=390mi/hr is the speed of the airplane.
There are 8 games played at the same time, and each team playes 15 round (plays every team but themselves. this means that the total amount of games is 8x15, which is 120 games
<span>X/9=-5
First: To get your x alone, and to get rid of your fraction you would multiply each side by 9.
You would get: x=-45 <That would be your answer
HOPE THIS HELPS! ^_^</span>
All you need to do is 125/13 so the correct answer is 9.61 Naturally I would round up so I would chose B. 10
