Question

Help check my answers?




Evaluate if w = –2.1 and z = 5.7.
w – z – 4

Answer 1

Alright, what do you think it is?

Answer 2

3.8

Answer 3

No.

Answer 4

It isn't because you have to replace the w and z with the numbers the represent. As a result of that, it should look like this -


-2.1 - 5.7 - 4 = ?

Answer 5

-7.6

Answer 6

Personally, since I know that my answer is going to be negative, I'll just add this all together, and then stick a negative sign up at the front.


2.1 + 5.7 + 4 = -(?)

Answer 7

I know my answer will be negative because you're starting with -2.1 and from there just making it smaller and smaller.

Answer 8

11.8

Answer 9

-11.8

Answer 10

Correct. and because we started with negative numbers, we can assume that the answer is -11.8
