(m-8) = -8m+29 i dont understand how to do the left side

-(m-8)= -8m+29

-1(m-8)=-8m+29Note: there is always an invisible 1 in front

-m+8=-8m+29Subtract both sides by -8

-m=-8m+21Add both sides by +m

0=-7m+21Add +7m to both sides

7m=21 Divide both sides by 7

m=3

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
