Question

write an expression that is equivalent to $4.5d + 10 - 1.5d - 2.5$. combine like terms to simplify. $4.5d + 10 - 1.5d - 2.5 = 4.5d + 10 + (-1.5d) + (-2.5) = 4.5d + (-1.5d) + 10 + (-2.5) =? +?$

Explanation:

Step1: Combine like terms for \(d\)

We have \(4.5d + (-1.5d)\). To combine these, we subtract the coefficients: \(4.5 - 1.5 = 3\), so this simplifies to \(3d\).

Step2: Combine like terms for constants

We have \(10 + (-2.5)\). Subtracting these, \(10 - 2.5 = 7.5\), so this simplifies to \(7.5\).

Answer:

\(3d + 7.5\)
