Question

42-b-(-b+36.4) (-8.4a)-(a+14.9)

Answer 1

42 - b - (-b + 36,4) = 42 - b + b - 36,4 = 42 - 36,4 = 5,6

(-8,4a) - (a + 14,9) = -8,4a - a - 14,9 = -9,4a - 14,9

Answer 2

To simplify the expression, let's go step by step:

1. Distribute the negative sign in the expression -b + 36.4:

   -b + 36.4 = -b + 36.4

2. Simplify the expression 42 - b - (-b + 36.4):

   42 - b - (-b + 36.4) = 42 - b + b - 36.4

   The 'b' terms cancel each other out:

   42 - 36.4 = 5.6

3. Simplify the expression -8.4a - (a + 14.9):

   -8.4a - (a + 14.9) = -8.4a - a - 14.9

   Combine the 'a' terms:

   -9.4a - 14.9

So the final simplified expression is:

5.6 - 9.4a - 14.9

You can further simplify this by combining the constant terms:

5.6 - 14.9 = -9.3

Thus, the simplified expression is:

-9.3 - 9.4a
