Let's start by simplifying the expression step by step:
-0.6•(1.6•(-9) - 5)= -0.6•(-14.4 - 5)= -0.6•(-19.4)= 11.64
(2.9•(-9) - 8)= 2.9•(-9) - 8= -26.1 - 8= -34.1
4•(4 - 1.5•(-9))= 4•(4 - (-13.5))= 4•(4 + 13.5)= 4•17.5= 70
Putting it all together:
11.64 - 34.1 - 70= -92.46
Therefore, the final answer is -92.46.
Let's start by simplifying the expression step by step:
-0.6•(1.6•(-9) - 5)
= -0.6•(-14.4 - 5)
= -0.6•(-19.4)
= 11.64
(2.9•(-9) - 8)
= 2.9•(-9) - 8
= -26.1 - 8
= -34.1
4•(4 - 1.5•(-9))
= 4•(4 - (-13.5))
= 4•(4 + 13.5)
= 4•17.5
= 70
Putting it all together:
11.64 - 34.1 - 70
= -92.46
Therefore, the final answer is -92.46.
