When you're simplifying equations, you have to collect the like terms (the similar ones, eg- fractions would be like terms, and so would letters).
When you're simplifying, you also have to take note of the operation before the equation.
1) Firstly, collect the like terms of M (M and -4M). As M comes before -4M, you have to add -4M to M. As -4M is a negative, this overwrites the addition, and this becomes M-4M. This then gives you -3M. The same applies to the fractions, as you have -1/6 + 5/6, you have to add 5/6 to -1/6, and this gives you 4/6, or 2/3 simplified. Therefore, you put these together- and this gives you -3M + 4/6, however, you normally have a negative number second, so one this has been rearranged, this gives you 4/6-3m.
2). Same applies to this one, you also have to collect the like terms of W. 2.3W and -3W. You simply have to subtract -3W from 2.3W, and this gives you -0.7W. You now have to collect the numbers, and you have -7 and 8. 8 is a positive, therefore, you have to add 8 to -7, giving you 1. Therefore, when you collect the like terms, this gives you -0.7W+1. As aforementioned, you cannot have a negative first, so one this is rearranged, this gives you 1-0.7W
Hope this helps :)
There are a lot of myths about the $2.00 bill. Some believe that there are so few of the bill made because John Hanson (1791-?), a black Liberian senator, is portrayed on the back of the bill. Evidence suggests that this John Hanson is portrayed on the back of the bill, but is not the same as the John Hanson (1721-1783) that is a presiding officer of the Continental Congress. Supposedly, the John Hanson from the Continental Congress is from an earlier era than the black Liberian senator. John Hanson, the black Liberian senator" is believed to be portrayed on the $2 bill because it wasn't commercially introduced until 1839. This cannot be proven because there are strong claims to both sides of the argument. However, in the original painting, there is no black man.
