Question

Evaluate − a + ( − b ) −a+(−b) where a = 6 . 0 5 a=6.05 and b = 3 . 6 1 1 b=3.611.

Answer 1

Answer:

-19.322

Step-by-step explanation:

− a + ( − b ) −a+(−b)

First step is to combine like terms

-a -a + -b + -b

-2a -2b

We know a = 6.05 and b = 3.611

-2 (6.05)  -2(3.611)

-12.1 - 7.222

-19.322
