Question

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

Explanation:

Step1: Group like terms (d terms and constant terms)

\(4.5d + (-1.5d) + 10 + (-2.5)\)

Step2: Combine d terms

\(4.5d - 1.5d = 3d\)

Step3: Combine constant terms

\(10 - 2.5 = 7.5\)

Step4: Form the equivalent expression

\(3d + 7.5\)

Answer:

\(3d + 7.5\) (or the grouped form before combining: \((4.5d - 1.5d) + (10 - 2.5)\))
