Answer:
300 mph
Step-by-step explanation:
Let s represent the initial speed of the plane in miles per hour. Then s-40 is the reduced speed after encountering the head wind. The time spent flying against the head wind was 5 - 2 = 3 hours.
... distance = speed×time
... 1380 = s×2 + (s -40)×3
... 1380 = 5s -120 . . . . . . . . . eliminate parenthses
... 1500 = 5s . . . . . . . . . . . . . add 120
... 300 = s . . . . . . . . . . . . . . . divide by 5
So he made 18 muffins for each of his friends and he has none left
so it can be divided by :
2 friends.....18/2 = 9...each getting 9 muffins
3 friends.....18/3 = 6...each getting 6 muffins
6 friends.....18/6 = 3...each getting 3 muffins
9 friends.....18/9 = 2...each getting 2 muffins
18 friends...18/1 = 18...each getting 1 muffin
K=2.5
1*2.5=2.5
2*2.5=5
3*2.5=7
4*2.5=10
To find a vertical asymptote set the denominator = to zero.
x + 2 = 0
x = -2
The vertical asymptote is at x= -2
There are 16 ounces in one pound
So it would be p=16z
