Question

1. which shows an expression equivalent to 6x + 8.25 − 4.5x? a 1.5x − 8.25 b 10.5x + 8.25 c 1.5x + 8.25 d 10.5x − 8.25

Explanation:

Step1: Combine like terms (x terms)

We have the expression \(6x + 8.25 - 4.5x\). First, combine the \(x\)-terms: \(6x - 4.5x\).
\(6x - 4.5x = (6 - 4.5)x = 1.5x\)

Step2: Rewrite the expression

After combining the \(x\)-terms, the remaining term is \(+ 8.25\). So the simplified expression is \(1.5x + 8.25\).

Answer:

C. \(1.5x + 8.25\)
