Answer:
see the explanation
Step-by-step explanation:
Let
x ---> the number of minutes you can spend on each of the other 4 subjects
we know that
The number of minutes you spend on math plus the number of minutes you can spend on each of the other 4 subjects must be less than or equal to 3 hours
Remember that
3 hours=3(60)=180 minutes
so
The inequality that represent this situation is
[tex]45+4x\leq 180[/tex]
solve for x
Subtract 45 both sides
[tex]4x\leq 180-45[/tex]
[tex]4x\leq 135[/tex]
Divide by 4 both sides
[tex]x\leq 33.75\ min[/tex]
therefore
The maximum number of minutes you can spend on each of the other 4 subjects must be less than or equal to 33.75 minutes
