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
Homes on East Egg are wealthy from long lines of generations (a son will inherit his father's fortune), whilst homes on West Egg are people who built up their fortunes (ex. people who gain money from working in industries).
The correct sentence is the second one "She built a high-performance CPU".
The first sentence should not contain a comma and is incorrect. The third sentence is incorrect because there shouldn't be a dash before CPU. The fourth sentence is incorrect because CPU is not written with dashes.
