Question

Evaluate each expression for a = -2,b = -4.1, and c = 5.


-c + b – a

Answer 1

`-c+b-a=?\\\\substitute\ values:\\ a=-2,\ b=-4,1\ c=5\\\\ -c+b-a=-5+(-4,1)-(-2)=-5-4,1+2=-9,1+2=\\\boxed{-7,1}`

Answer 2

For this question, you can substitute in all the values for the variables.
-c + b - a
= -(5) + (-4.1) - (-2)
= -5 - 4.1 + 2
= -9.1 + 2
= -7.1

Hope this helps! :)
