Part B:
The solution in Part 1 is -39.1, so we can berak this result in tens, ones and theths so:
So if we sum the we have the same answer
Part C:
the operation we can rewrite is:
and using the distribution propertie we can write it like:
Part D:
and then we operate using the assosiative propertie:
Part E:
Finally we simplyfy the expression:
Part F:
now he meassure the temperature of the water and it dropes -0.6 Fº so we have to rest this to the last temperature so:
