[Done] Keitaro walks at a pace of 3 miles per hour and runs at a pace of 6 miles per hour. Each month, he wants to complete at least 36 miles but not more than 90 miles. The system of inequalities represents the number of hours he can walk, $w$, and the number of hours he can run, $r$, to reach his goal. [tex]\begin{array}{l} 3 w+6 r \geq 36 \\ 3 w+6 r \leq 90 \end{array}[/tex] Which combination of hours can Keitaro walk and run in a month to reach his goal? A. 2 hours walking; 12 hours running B. 4 hours walking; 3 hours running C. 9 hours walking; 12 hours running D. 12 hours walking; 10 hours running

[Done] Heather writes the equations below to represent two lines drawn on the coordinate plane. [tex]\begin{aligned} -6 x+18 y & =0 \\ 4 x-12 y & =20 \end{aligned}[/tex] After applying the linear combination method, Heather arrived at the equation [tex]$0=60$[/tex]. What conclusion can be drawn about the system of equations? A. The equation has no solution; therefore, the system of equations has no solution. B. The equation has a solution at [tex]$(0,60)$[/tex]; therefore, the system of equations has a solution at [tex]$(0,60)$[/tex]. C. The equation has infinite solutions; therefore, the system of equation as infinite solutions. D. The equation has a solution at [tex]$(0,0)$[/tex]; therefore, the system of equations has a solution at [tex]$(0,0)$[/tex].
