0.25r- 0.125 + 0.5r= 0.5 +r
0.75r- 0.125= 0.5 +r       ------ combine like terms
        + 0.125 + 0.125      ------- isolate the variable
0.75r = 0.625 + r
- r                     - r          ------- combine like terms
-0.25r= 0.625
/-0.25   /-0.25               -------divide both sides by -0.25
         r= -2.5

Bonus: Mr. Rao is planning on making a shed in his backyard (see his plan in the image below). However, local laws require sheds
Leviafan [203]

Answer:

North 10 feet, and East 5 feet.

Step-by-step explanation:

So we know that North is ^ way. We also know that East is > way.

These are the two directions we must go, since the property line is both South and West of the shed.

The shed is 10ft East of the property line, and we must be 15ft in that direction. So we must go another 5ft East.

Now, the shed is 5ft North of the property line, and we must be 15ft in that direction. So we must go another 10 feet North.

Hope this helps!
