write an expression that is equivalent to 4.5d + 10 - 1.5d - 2.5. which expression shows 4.5d + 10 - 1.5d - 2.5 written as a sum? 4.5d + 10 + (-1.5d) + (-2.5) 4.5d + 10 + 1.5d + 2.5
Answer
Explanation:
Step1: Combine like - terms of the variable $d$.
$4.5d-1.5d=(4.5 - 1.5)d=3d$
Step2: Combine the constant terms.
$10-2.5 = 7.5$
Step3: Write the equivalent expression.
The equivalent expression is $3d + 7.5$
Answer:
- $3d + 7.5$
- $4.5d+10+(-1.5d)+(-2.5)$
