Question

For each expression, rewrite the expression to illustrate addition only. Evaluate eachexpression, if possible.A.-6 + 15 - 18 - 2B.2m – 8m - 9 - 1/2p

Answer 1

SOLUTION

A.

$\begin{gathered} -6+15-18-2 \\ to\text{ illustrate addition only, the expression will be written as } \\ (-6)+15+(-18)+(-2) \\ \end{gathered}$

To evaluate the expression further, we will have:

$\begin{gathered} (-6)+15+(-18)+(-2) \\ -6+15-18-2 \\ =-11 \end{gathered}$

B.

$\begin{gathered} 2m-8m-9-\frac{1}{2}p \\ to\text{ illustrate addition only, the expression will be written as } \\ (2m)+(-8m)+(-9)+(-\frac{1}{9}p) \end{gathered}$

To evaluate the expression further, we will have

$\begin{gathered} (2m)+(-8m)+(-9)+(-\frac{1}{9}p) \\ 2m-8m-9-\frac{1}{2}p \\ -6m-9-\frac{1}{2}p \end{gathered}$
