Answer:
(3,6)
Step-by-step explanation:
-(6x+2y=30)
x+2y=15
-6x-2y=-30
x +2y=15
-5x=-15
x=3
3+2y=15
2y=12
y=6
I believe that the correct measurement in feet is 1.4 x
10^5 feet. You forgot to include the ^5.
So since that is the measurement of 1 marathon, therefore
half a marathon would simply be also half of that, that is:
0.7 x 10^5 feet
or
7 x 10^4 feet
