Simplify 5m - m - m +3

3m + 3

Explanation: If there's no coefficient in front of the variable, you can give it a coefficient of 1, so the -m can be thought of as -1m.

So our problem can be read as 5m - 1m - 1m + 3.

Now combine like terms.

Since 5m, -1m, and -1m are terms that contain an m, we can combine.

So 5m - 1m - 1m simplifies to 3m.

So our answer is 3m + 3

ok thats very interesting

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6
