Answer:
4 miles
Step-by-step explanation:
<u>Walking:</u>
Distance = d miles
Rate = 4 mph
Time = t hours
<u>Biking:</u>
Distance = d miles
Rate = 10 mph
Time 
hours (convert minutes to hours)
Hence,
Therefore, the distance to friend's house is
and the total distance of the round trip is
If you want it to be y=mx+b form then the equations should look like this: y=x+5 and y=-1/3x+1.

A rhombus is a special case of a parallelogram, because it fulfills the requirements of a parallelogram: a quadrilateral with two pairs of parallel sides. It goes above and beyond that to also have four equal-length sides, but it is still a type of parallelogram.
P - q = 8.....multiply by -1
2p - q = 19
----------------
-p + q = -8 (result of multiplying by -1)
2p - q = 19
---------------add
p = 11
now we sub 11 in for p in either of the original equations to find q
p - q = 8
11 - q = 8
11 - 8 = q
3 = q
so ur solution is (11,3)
