Answer: 80 cm of chain weighs 2 kg.

Answer:

 W = 0.025L

Step-by-step explanation:

A piece of a chain's length and weight are in proportion.

If L represents the length in cm and weight is represented by W in kg, then we can write W = aL + b ........(1)

Now, if the length of the chin is 0, then the weight will also be 0. So, from equation (1), we can write W =aL ....... (2) as b becomes zero.

Now, the 320 cm of chain weighs 8 kg.

So, from equation (2), we get, 8 = 320a, ⇒ a = 0.025 kg/cm

So, the equation becomes W = 0.025L (Answer)

GI bisects DGH so that m DGI is x-3 and mIGH is 2x-13 find the value of x
baherus [9]

x = 10

since GI bisects ∠DGH then ∠DGI = ∠IGH, hence

2x - 13 = x - 3 ( subtract x from both sides )

x - 13 = - 3 ( add 13 to both sides )

x = 10
