Answer:
Allie got $120, Barbara got $240 and Carson got $80.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
Allie got x.
Barbara got y.
Carson got z.
Divide $440 among themselves
This means that
Barbara gets 2 times as much as allie.
This means that
Carson gets 1/3 as much as barbara.
This means that
Finding x:

Answer:
(a) y = -3/4x +36
Step-by-step explanation:
The slope of the rail is ...
m = rise/run = -9/12 = -3/4
The initial height of the rail is 36, so the slope-intercept equation for the rail is ...
y = mx +b . . . . . m = slope; b = initial value
y = -3/4x + 36
Average would be 60 miles per hour
