solve this inequality problem:
It is -6 degrees celcius outside. How many whole degrees can the temperature rise and still be less than 10 degrees Celcius??

increasing from - 6° Celsius to 9° celsius is a total of 15°
and less than 10° celsius

If it's an inequality problem, then this is how you do it:
Temp (T) has to be less than 10Ë C and still be a whole number. This means it has to be 9Ë C or less.
T + (-6) ⤠9
==> T - 6 ⤠9
==> T ⤠9 + 6
==> T ⤠15
So, T can increase by 15Ë and still be a whole number less than 10Ë, but the inequality shows that you can have any value less than 15Ë as well, but the max is 15Ë.
Hope this helps.

15 celsius
-6 + 15 = 9 degrees
