Question

Use properties of rational numbers to simplify the expression.

(37 - 17.13) - (186.4 + 4)
 A.
-136.27
 B.
-170.53
 C.
202.53
 D.
210.53

Answer 1

Let's simplify the expression step by step:

The expression is: \((37 - 17.13) - (186.4 + 4)\)

First, we can simplify each part inside the parentheses separately.

1. Simplifying \(37 - 17.13\):
\[
37 - 17.13 = 19.87
\]

2. Simplifying \(186.4 + 4\):
\[
186.4 + 4 = 190.4
\]

Now we can substitute these values back into the expression:
\[
19.87 - 190.4
\]

Next, we perform the subtraction:
\[
19.87 - 190.4 = -170.53
\]

Thus, the simplified expression is \(-170.53\).

The answer is **B. -170.53**.
