Answer:
the minus can get inside the brackets
Step-by-step explanation:
-2(n-3)= 2(3-n)= 6-2n
nothing
why would you change anything in (n-3)
it is in its simplest form
just distribute the -2
you can write it as (-2 x n) + (-2 x -3) if you want
Let x be the number of logs=18 hours
6 logs=4 hours
X*4=18*6
4x=108
x=27 logs
so therefore 27 logs are needed to keep the fire burning for 18 hours
The answer is 8/9
