Combine Like terms: 17 + 3a + 4b-5c-a +30
Please help!!

To combine like terms you want to only add or subtract the numbers with matching variables.

So 3a and -1a create 2a.

4b is the only b variable.

-5c is alone.

And 17 and 30 add to 47.

So our answer put in order would be:

2a+4b-5c+47

Hope this helps

10 you would take 50/ .2

step-by-step explanation:

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
