Question

4. -171 +1 -181 - 305. 4 (-1)(-4)6. -15(5)7. -72 = (-4)8. 210 • (-7).

Answer 1

The question is given below as

`-|7|+|-18|-30`

Step 1: Apply the absolute value rule for

`|a|=a,a\ge0`

That is,

`|7|=7`

Step 2: Apply the absolute value rule also

`|-a|=a`

That is,

`|-18|=18`

Step 3: Therefore, By combining all the values, we will have

`\begin{gathered} -|7|+|-18|-30 \\ =-7+18-30 \\ =-7-12 \\ =-19 \end{gathered}`

Hence,

The final answer is = -19
