Answer 2

To solve the expression, let's break it down step by step:

First, simplify the expression within the parentheses: 2.5 - 2 = 0.5 2/9 - 1.5 = -1.5

Now substitute the simplified values back into the expression: -4(0.5/-1.5) + 5.5 * 2/9 - 8

Next, simplify the multiplication and division within the expression: 0.5/-1.5 = -0.33 recurring (rounded to two decimal places) 5.5 * 2/9 = 1.22 recurring (rounded to two decimal places)

Substituting the simplified values into the expression: -4(-0.33 recurring) + 1.22 recurring - 8

Now calculate the values: -4(-0.33 recurring) = 1.33 recurring (rounded to two decimal places) 1.33 recurring + 1.22 recurring = 2.55 recurring (rounded to two decimal places)

Finally, subtract 8 from the result: 2.55 recurring - 8 = -5.45 recurring (rounded to two decimal places)

Therefore, the simplified value of the expression is approximately -5.45 (recurring).
