Question

solve for w: j = 4w note! it means isolate w. what do you need to do to the coefficient? -1/4 0.25 --0.25 4

Explanation:

Step1: Identify the equation

We have the equation \( j = 4w \). To isolate \( w \), we need to perform an operation on the coefficient of \( w \), which is 4.

Step2: Determine the operation

Since \( w \) is multiplied by 4, we use the inverse operation of multiplication, which is division. We divide both sides of the equation by 4 (or multiply by \( \frac{1}{4} \), which is equivalent to 0.25).
Dividing both sides by 4: \( \frac{j}{4}=w \) or \( w = 0.25j \). So the operation on the coefficient (4) is to multiply by \( \frac{1}{4} \) (or divide by 4), and \( \frac{1}{4}=0.25 \).

Answer:

0.25 (or \( \frac{1}{4} \), but among the options, 0.25 is the correct choice for the operation on the coefficient to isolate \( w \))
