It isn’t asking you to answer the question, all you need to do is simplify it

This is something called collecting like terms, for example, we’d combined both of the r terms

4r - r = 3r

And combine both of the constant terms

14 - 6 = 8

The final expression will be 3r + 6

Decrease 248 by 30%

Snowcat [4.5K]

Okay this equation really says is what is 30% of 248.

So, lets convert 30% to a fraction, 3/10 which is easier to work with.

All you have to do now is get out a calculator and do 248 *3/10 (or .3) and get 74.4

So subtract 74.4 and get

173.6
