1.
1 mile= 30 seconds
(1,30)
6 miles= 1 1/2 minutes
6 miles=90seconds

hope its right
She will have $500 in 5 days because when she takes out the 20 every week she will have had $100 so to make $500 she will have to have made 5 $100
8 feet, because 10^{2} - 6^{2} = 64;
\sqrt{64} = 8[tex]
Combine like terms
-2x-4=-2x-4
Since the equations are the same, the answer is infinitely many solutions.
