Simplifying the Expression: (3-8y)*(-2.5)

This expression involves multiplication and subtraction. Let's break down how to simplify it step by step.

Understanding the Order of Operations

We need to follow the order of operations (PEMDAS/BODMAS) to correctly simplify the expression:

  • Parentheses / Brackets
  • Exponents / Orders
  • Multiplication and Division (from left to right)
  • Addition and Subtraction (from left to right)

Simplifying the Expression

  1. Parentheses: We start by simplifying the expression inside the parentheses:

    • (3 - 8y) remains as it is.

  2. Multiplication: Now we multiply the entire expression inside the parentheses by -2.5.

    • Remember that multiplying a negative number with a positive number results in a negative number.

    We get:

    • -2.5 * (3 - 8y) = (-2.5 * 3) + (-2.5 * -8y)

  3. Simplifying further:

    • -2.5 * 3 = -7.5
    • -2.5 * -8y = 20y

  4. Final Expression: Combining the terms, we get the simplified expression:

    • -7.5 + 20y

Conclusion

Therefore, the simplified form of (3-8y)*(-2.5) is -7.5 + 20y. This expression can't be simplified further unless we have a specific value for 'y'.
