Answer 2

Simplifying the Expression

To simplify the given expression: 6.5c + 30 - 6.5c - 71 + 2.7v - 7.5 - 5v + 7.5, we can combine like terms.

Solution

1. Combine like terms: - 6.5c - 6.5c simplifies to 0. - 2.7v - 5v simplifies to -2.3v. - 30 - 71 - 7.5 + 7.5 simplifies to -41.

2. After combining like terms, the simplified expression is: - 0 - 41 - 2.3v - Which further simplifies to -41 - 2.3v.

So, the simplified expression is -41 - 2.3v.

This simplification is based on the principles of combining like terms in algebraic expressions.
