Julie travelled with 30.5 miler per gallon.
<u>SOLUTION:
</u>
Given, On Julie's trip to the mountains she traveled 192 miles using 6 gallons of gas.
On the return trip she traveled 235 miles on 8 gallons of gas.
We have to find how many miles per gallon did Julie get on the way there?
We know that,
Substituting the values we get,
Hence, Julie travelled with 30.5 miler per gallon on the way there on mountains.

X= 9 1/4 or 9.25 in decimal form
The coordinates for D are (-4, -7)
First we must locate point B as it is vital to finding the midpoint of BD. To do this, we take the average of the endpoints AC since B is its midpoint.
x values = -9 + 1 = -8
Then divide by 2 for the average -8/2 = -4
y values = -4 + 6 = 2
Then divide by 2 for the average 2/2 = 1
Therefore B must be (-4, 1)
Now we know the values of E must be the average of B and D. So we can write equations for each coordinate since we know they are averages.
x - values = (Bx + Dx)/2 = Ex
(-4 + Dx)/2 = -4 ---> multiply both sides by 2
-4 + Dx = -8 ---> add -4 to both sides
Dx = -4
y - values = (By + Dy)/2 = Ey
(1 + Dy)/2 = -3 ---> multiply both sides by 2
1 + Dy = -6 ---> subtract 1 from both side
Dy = -7
So the coordinates for D must be (-4, -7)
