5280 feet in 1 mile
3600 seconds in an hour
58(5280) / 3600 = 306240/3600 = 85.06 ft per sec or if u need it rounded, it is 85.1
We're going to solve each of the systems to determine the solution.
<u>System
</u>

using a graph tool
the solution is the line 
see the attached figure N 
<u>System
</u>

using a graph tool
the solution is the shaded area
see the attached figure N 
<u>System
</u>

using a graph tool
The system has no solution

<u>System
</u>

using a graph tool
the solution is the shaded area
see the attached figure N 
therefore

I can’t really graph on this but place a dot on the four on the y axis and go up one and over two and place a dot there. just keep repeating it till u get to the end of the graph :)
Whats the diameter?
1/8(3.14) = 0.3925
1/3 + 3/7
save + fun + extra
(7/21 + 9/21) = 16/21 on save and fun
