Answer:
-12.0
Step-by-step explanation:
From the above question, we are given:
−7.6 − 2[9 + (−6.8)]
We apple the PEDMAS rule
P = Parentheses, Hence:
Step 1
The first step is to simplify the parentheses
[9 + (−6.8)] = 2.2.
Step 2
We now have:
−7.6 − 2(2.2).
Step 3
We simplify Parentheses again
(- 2)2.2 = -4.4
Step 4
We simplify
-7.6 - 4.4
= -12.0
The final answer is 12.0
