Consider the attached ellipse. Let the sun be at the right focus. Then perihelion is at right vertex on the x-axis and aphelion is at the left vertex on the x-axis.
The distances:
- from perihelion to the sun in terms of ellipse is a-c;
- from aphelion to the sun in terms of ellipse is a+c.
Then
Add these two equations:
and subtract first equation from the second:
Note that 
thus
The equation for the planet's orbit is
Answer:
9
Step-by-step explanation:
Using the property that

Answer:
x=75
Step-by-step explanation:
Hey There!
If you didn't know the exterior angle of a triangle is equal to the sum of the opposite interior angles of a triangle
So essentially what I'm saying is that
2x-5=70+x
step 1 add 5 to each side
-5+5 cancels out
70+5=75
now we have
2x=70+x
step 2 subtract x from each side
x-x cancels out
2x-x=x
we're left with
x=75
Answer:
x= 
Step-by-step explanation:
mutiply both sides of the equation by 6
12x-2n=3
move the bariable to the right hand side and change its sign
12x=3+2n
divide both sides
x=
+1/6n
use commutative propert to reorder the terms
x= 1/6n +
and thats it, i hope this helps ya!
