Arope stretches directly depending on the load it must carry. a load of 8 pounds stretches the rope 9.6 inches. if a rope stretches 6 inches, then it is holding a load

A rope stretches 6 inches, then it is holding a load of 5 pounds.

Step-by-step explanation:

Given : A rope stretches directly depending on the load it must carry. A load of 8 pounds stretches the rope 9.6 inches. If a rope stretches 6 inches.

To find : What is holding a load of ?

Solution :

Applying unitary method,

When the rope is stretched by 9.6 inches, then the amount of load it is holding is 8 pounds.

When the rope is stretched by 1 inch, then the amount of load it is holding is

Now, The rope is stretched by 6 inches, then the amount of load it is holding is given by

i.e.

Therefore, A rope stretches 6 inches, then it is holding a load of 5 pounds.

answer: 88

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
