-1/2(7w+4)+1/5(5w-15)
please explain how to solve. thank you

Step-by-step explanation:

Is this the correct statement?

If so, here's how. While we're here, you don't actually "solve" an expression, you can only simplify it. Solving it implies solving an equation, and that needs an = sign.

Starting on the left. First, distribute the fraction over the parenthesis:

Then, do the same thing on the right. Distribute the fraction over the parenthesis again:

Here, on the right, 5 and 15 have a common factor of 5. Factor that out:

Finally, cancel out the 5s:

That's as simplified as it gets.

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.
