, can we subtract -2.5 - 3.5n? *
yes
but in order to evaluate it, you need to have a value for n.
Otherwise, there's no way to simplify it in any helpful way.
Yes, we can subtract -2.5 - 3.5n. To perform the subtraction, follow these steps:
1. Start with the expression: -2.5 - 3.5n
2. To subtract -2.5, simply subtract it from 0 (since -2.5 is the negative of 2.5). This gives us:
0 - 2.5 = -2.5
3. Now, to subtract 3.5n, we need to be careful since n is a variable. Since we do not have any information about the value of n, we cannot simplify it further. So, we keep the term as it is:
-2.5 - 3.5n
Therefore, the final result of subtracting -2.5 - 3.5n is -2.5 - 3.5n.
