Final answer:
To simplify the given expression, you combine like terms and simplify within the parenthesis to get a final simplified version of the expression: 1940 + 0.48Y. To find the value, you substitute the given value of y into the simplified expression.
Step-by-step explanation:
The original question seems to be asking how to simplify and solve an expression given certain values for the variable y. Although the provided information contains various solution steps for different expressions, one is related to simplifying algebraic expression:
140 + 0.9(Y - 0.3Y) + 400 + 800 + 600 - 0.15Y.
When simplified, this equation becomes:
- Combine like terms: 140 + 400 + 800 + 600 = 1940
- Simplify the expression within the parenthesis: 0.9Y - 0.27Y = 0.63Y
- Subtract 0.15Y from 0.63Y: 0.63Y - 0.15Y = 0.48Y
- Add this to the constant term: 1940 + 0.48Y
So, the simplified expression is 1940 + 0.48Y. To find the value of this expression for a given value of y, you would substitute the given value into the expression and calculate the result.
