Question

Pls explain why no pls and thank u​

Answer 1

No, because c = 1.8 would be wrong and the real answer would be c < 1.8

Explanation:

Answer 2

Explanation:

So we have : c + 2.5 < 4.3

And it's asking whether c = 1.8 is a solution.

Substitue c = 1.8 in, we get :

1.8 + 2.5 < 4.3
4.3 < 4.3 (not true)

So, c = 1.8 is NOT a solution.
