Answer:
The slope is 2
Step-by-step explanation:
There's a theorem: 
So lets put that into our equation.
which also equals 
Then, all we must do is divide the nominator from the denominator.
6/3 = 2
Therefore, the slope is 2!
I hope this helps!
M + w = 253m + 4w = 90 Let's do substitution, first by solving the first equation for m. m = 25 - w Substitute! 3(25 - w) + 4w = 9075 - 3w + 4w = 90w = 15 m = 25 - 15 = 10 Hope this helps!
Answer:
For 3/2 of the speed = <em>292.5 minutes</em>
For 3/4 of the speed = <em>146.25 minutes</em>
Step-by-step explanation:
It takes 3hrs 15 minutes to fly from A to B
From A to B = 180minutes + 15 minutes
= 195 minutes (At constant speed)
At constant speed,
<em>If the speed is 3/2 of the original speed,</em>
<em>It will be,</em>
<em>3/2 X (195 minutes) = 585 / 2 = </em><u><em>292.5 minutes</em></u>
<u><em></em></u>
<em>On the other-hand,</em>
<em></em>
<em>If the speed is 3/4 of the original speed,</em>
<em>3/4 X (195 minutes) = 585 / 4 = </em><u><em>146.25 minutes</em></u>
