Which expression is equivalent to
185-1-225
-40
A. 183-22-40
O B. 18$+(-222)+(-40)
OC. –18–22% +40
D. 183+222 +40

Answer 1

In order to find the equivalent expression, let's use the following property:

`a-(-b)=a+b`

In other words, when subtracting a negative number, we can just add the corresponding positive number, that is, switch the two negative signs for a positive sign.

So we have that:

`\begin{gathered} 18(1)/(5)-(-22(2)/(5))-(-40(1)/(5)) \\ =18(1)/(5)+22(2)/(5)+40(1)/(5) \end{gathered}`

Therefore the correct option is D.
