N/5 - 7 = -11
n/5 - 7 (+7) = -11 (+7)
n/5 = -4
n/5 (5) = -4(5)
n = -20
hope this helps
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:
No
Step-by-step explanation:
Water isn't wet by itself, but it makes other materials wet when it sticks to the surface of them.

I think 6:8:0 is a possible answer for the first question, Math isn’t my greatest subject
