Answer:
The height of water in the cylinder after drooping 8 marbles is 12 mm
Step-by-step explanation:
∵ The change of the height of the water varies directly with the change of the number of marbles
∵ (h2 - h1) α (x2 - x1)
∴ (h2 - h1) = k (x2 - x1)
∴ (11 - 10) = k (6 - 4)
∴ 1 = 2 k
∴ k = 1/2
∴ (h2 - h1) = 1/2 (x2 - x1)
∴ (Δh) = 1/2 (Δx)
∴ h3 - 11 = 1/2 (8 - 6)
∴ h3 = 1/2 × 2 + 11 = 12 milliliter

Answer:
(a-c)/b = x
Step-by-step explanation:
a = bx + c
subtract 'c' from each side to get:
(a-c) = bx
divide each side by 'b' to get:
(a-c)/b = x
