Collin generates an expression equivalent to 7w−5+x−3(w+5)−x and writes it in its simplest form. What is the coefficient of the variable w?(1 point)
3 answers
The coefficient of the variable w is -3, because we subtract 3(w+5), which simplifies to -3w-15.
wrong
Apologies for the error.
To simplify the expression 7w - 5 + x - 3(w+5) - x, we can first simplify the terms within the parentheses:
7w - 5 + x - 3w - 15 - x
Next, we can combine like terms by combining the w terms and the x terms:
(7w - 3w) + (-5 - 15) + (x - x)
This simplifies to:
4w - 20
Therefore, the coefficient of the variable w is 4.
