combine like terms to simplify.\n4.5d + 10 - 1.5d - 2.5 = 4.5d + 10 + (-1.5d) + (-2.5)\n= 4.5d + (-1.5d) + 10 + (-2.5)\n= ? + ?
Answer
Explanation:
Step1: Combine like terms with variable (d)
[ \begin{align*} 4.5d+(-1.5d)&=(4.5 - 1.5)d\ &=3d \end{align*} ]
Step2: Combine constant terms
[ \begin{align*} 10+(-2.5)&=10 - 2.5\ &=7.5 \end{align*} ]
Answer:
(3d+7.5)
