Question

Use properties of rational numbers to simplify the expression.

(30 - 10.13) - (192.4 + 7)
A.
205.53
B.
219.53
C.
-179.53
D.
-159.27

Answer 1

First, we can simplify the expression inside the parentheses on the left side:

(30 - 10.13) - (192.4 + 7) = 19.87 - (192.4 + 7)

Next, we can simplify the expression inside the parentheses on the right side:

19.87 - (192.4 + 7) = 19.87 - 199.4

Now, we can subtract 19.87 from 199.4 to find the final answer:

19.87 - 199.4 = -179.53

Therefore, the simplified expression is -179.53. The answer is option C.
