Final answer:
The expression 0.4s + 600 - 600 - 1400 - 600 simplifies to 0.4s - 2000 by combining like terms. A similar approach is used to simplify the more complex given expression to 1940 + 0.48Y.
Step-by-step explanation:
The property being asked about seems related to the simplification of an expression in mathematics. To simplify the expression 0.4s + 600 - 600 - 1400 - 600, we can combine the like terms. The constants can be added or subtracted from each other. In this case, if we add 600 and subtract 600, these two operations cancel each other out, leaving us with 0.4s - 1400 - 600. Combining -1400 and -600 gives us 0.4s - 2000.
Now let us look at the supplied reference expressions:
- Starting with 140 + 0.9(Y - 0.3Y) + 400 + 800 + 600 - 0.15Y, we can simplify by combining like terms.
- Distribute the 0.9 into the parentheses: 140 + 0.9Y - 0.27Y + 400 + 800 + 600 - 0.15Y.
- Combine the Y terms: 0.9Y - 0.27Y - 0.15Y becomes 0.48Y.
- Add the constants: 140 + 400 + 800 + 600 becomes 1940.
- The simplified expression is 1940 + 0.48Y.
In conclusion, the property used here involves combining like terms and distributing multiplication over addition and subtraction.
