2.8 mi
3.3mi
4.8+7(3)=8+21=29mi
5.yes, she hikes continuously so distance can be fractional parts of a mile
7.y=12x+120, y=12(5)+120=180
8.y=6.5x+10,6.5(10)+10=75
Answer:
4, 1, 3, 6, 2, 5
Step-by-step explanation:
Start by drawing a circle (4).
Pick a point on the circle (1).
Draw an arc from that point (3).
Draw another arc the same distance from the first (6).
Repeat around the circle (2).
Connect the dots (5).

You should actually do this construction some time. It will take the mystery out of the sequence of steps.
Multiply one of them by -1 so one of the -2y is positive
-1(-7x-2y=-13)=7x+2y=13
Then add the two equations
7x+2y=13
+ x-2y=11
========
8x=24 - the 2y and -2y cancel out. Now solve for x
x=3 Now plug the x back into one of the equations
3-2y=11 Now solve for y
-2y=11-3
-2y=8
y=-4
So x=3 and y=-4
Hope this helps!
