In order to answer this question let's suppose,
Joe is x miles from the beginning and y miles from the end. These assumptions are necessary to answer further:
Now,
x=2y
x+y=30
plugging in x=2y in the above equation
2y+y=30
3y=30
y=10
Hence, according to our calculations, Joe has to hike 10 miles further
Answer:
13x
because you would comibne like terms, so you add the 8 and 5.

Answer:
![y=-4; y=28](https://tex.z-dn.net/?f=y%3D-4%3B%20y%3D28)
Step-by-step explanation:
The way I like to think about it, with absolute value meaning the distance is
"find which number are 16 apart from 12". Which means 28 (to the right) or -4 (to the left).
More formally, applying the definition of absolute value,
![|y-12|=16 \leftrightarrow y-12=\pm16\\y-12=-16 \rightarrow y=-4\\y-12=+16 \rightarrow y=28](https://tex.z-dn.net/?f=%7Cy-12%7C%3D16%20%5Cleftrightarrow%20y-12%3D%5Cpm16%5C%5Cy-12%3D-16%20%5Crightarrow%20y%3D-4%5C%5Cy-12%3D%2B16%20%5Crightarrow%20y%3D28)
