3w-10w
A. 13w
B. -7w
C. -7
D. 7w
well, 3-10 = -7, so ...
To simplify the expression 3w - 10w, we need to combine like terms. In this case, the like terms have the same variable, which is "w".
To combine like terms, we need to add or subtract the coefficients (numbers in front of the variable). In this case, we have 3w and -10w. To combine them, we subtract the coefficients:
3w - 10w = (3 - 10)w = -7w
Therefore, the simplified expression is -7w.
So, the correct answer is option B: -7w.
To simplify the expression 3w - 10w, we can combine like terms by subtracting the coefficients of w.
3w - 10w = (3 - 10)w = -7w
Therefore, the simplified expression is -7w.
The correct answer is option B. -7w.
