Answer:
first stage=420km
second stage=360Km
Step-by-step explanation:
Hi!
To solve the problem follow the steps below
1. We will call X to the first stage and Y to the second stage.
2. Raise the equations taking into account the following
the sum of both stages is 780km
X+Y=780km
the first stage has 60km more than the second
Y+60=X
X-Y=60
3. Add the equations found above
X + Y =780
X - Y =60
------------------------
2X=840
Solving for X=840/2=420Km
use one of the equations obtained in step 2, to get the value of Y
Y+60=X
X-60=Y
420-60=Y
Y=360km
Answer:
y = -1
Step-by-step explanation:
As we move from point (-5, -1)
to point (2, -1), x increases by 7 and y stays the same.
The slope of this line is thus m = [-1 - (-1)] / 7, or just m = 0.
This is a horizontal line. Its equation is y = -1.

Answer:
y= 21
Step-by-step explanation:
-7/12=y/-36
Switch sides
y/-36=-7/12
Multiply both sides by -36 and simplify
y=21
Hope this helped! :)
