How can -6.75 + (10.25) be expressed as the sum of its integer and decimal parts
ArbitrLikvidat [17]

Answer:

 -6.75 + (10.25)    =  ( (-6)  + (10))  + ( (-0.75) + (0.25))

Here, the integer part  =     ( (-6)  + (10))

Decimal part =   ( (-0.75) + (0.25))

Step-by-step explanation:

Here, the given expression is:    -6.75 + (10.25)

Now, -6.75  = (-6)  +  (-0.75)

Also, (10.25)  = (10)  + (0.25)

So, the expression can be written as

 -6.75 + (10.25)  =  (-6)  +  (-0.75) +  (10)  + (0.25)

                           = ( (-6)  + (10))  + ( (-0.75) + (0.25))

or,   -6.75 + (10.25)    =  ( (-6)  + (10))  + ( (-0.75) + (0.25))

Where the integer part is    ( (-6)  + (10))

and the decimal part is  ( (-0.75) + (0.25))

bearhunter [10]
-4.2 degrees. What you would do is from 8-12 (midnight) is 4 hours. So it dropped -16.8 degrees in those 4 hours so -16.8 / 4 is -4.2 degrees. So it dropped -4.2 degrees every hour but it was also -4.2 degrees at 9:00 p.m.
