Answer:
The number of days when Kimmy play for two hours a day is 3.
Step-by-step explanation:
Let the number of days when Kimmy play for two hours a day be x. So, the number of days when Kimmy play for three hours a day is 9-x.
It is given that Kimmy has played video games 24 hours over the last 9 days.
[tex]2(x)+3(9-x)=24[/tex]
[tex]2x+27-3x=24[/tex]
[tex]-x+27=24[/tex]
Subtract 27 from both the sides.
[tex]-x=24-27[/tex]
[tex]-x=-3[/tex]
[tex]x=3[/tex]
Therefore the number of days when Kimmy play for two hours a day is 3.
