(0, 0) → t = 0, w = 0 → w = 0 · 0

(1, 4) → t = 1, w = 4 → w = 1 · 4

(2, 8) → t = 2, w = 8 → w = 2 · 4

(3, 12) → t = 3, w = 12 → w = 3 · 4

<h3>Answer: w = 4t</h3>

What is the answer to 3x+x/4=x+3/4
erica [24]

Answer:x = 1

Step-by-step explanation:

3x + x/4 = x + 3/4

Subtract x from each side

2x + x/4 = 3/4

Times each side by 4

The 4 beneath the x cancels out

3/4 x 4 = 3

2x + x = 3

3x = 3

Divide each side by 3

x = 1
