-1.5 + 7.5
factor out -1.5, divide 7.5 by 1.5 to factor it out of it as well (7.5 divided by -1.5) and make sure you get NEGATIVE 5.
-1.5(1 x -5)
I believe it would just be b=1m or b=m. the reason i added the 1 in front of the m was to show you that the books would equal 1 per month. b and m are equal to each other because the rate is 1 book per 1 month.
Factor 16 and 45 and find the common ones
16=1*2*2*2*2
45=1*3*3*5
common one is 1
gcf=1
Letter D I hope that’s what I know
