0.3(r+2)= -0.1(-2r-4) can you solve this show your work

0.3r + 0.6= 0.2r + 0.4
-0.2r. -0.2r

0.1r + 0.6= 0.4
-.6 -0.6
0.1r= -0.2
R = -2

The decimals in front of the parentheses can be distributed to the number inside giving us: .3r-.6=.2r-.4

Then we combine like terms, and it doesn't matter what side you move what to: .1r=2

Now that we have reached this point we divide both sides with the number in front of 'r': .1r/.1=2/.1

After you do that, we have our r=20

Hope this helped you out! :)

40 because it’s just a little longer than 32 feet
