Answer:
-3, -2, -1, 0, 1, 2, 3
Step-by-step explanation:
Answer:
->a is 2
->b is one eight
Step-by-step explanation:
one fourth dividen in two becomes one eight.
Write a system of equations:
x + y = 125
20x + 15y = 2100
Solving:
x = 125 - y
20(125 - y) + 15y = 2100
2500 - 20y + 15y = 2100
2500 - 5y = 2100
-5y = 2100 - 2500
-5y = -400
y=80
x + 80 = 125
x = 125 - 80
x = 45
The first charges 45$ per hour and the second charges 80$ per hour
4+3+1+1+1+1+1 =12
4x3x1x1x1x1x1=12
I think around 44% chance that all three flights would arrive on time, but i'm not that sure.
