Question

The length of 2/3 of a rope is (4u-5) express the total length of a rope in u

Answer 1

The total length of rope expressed in terms of u is :

6u = 8.5

How to express the total length in terms of u

Using the equations given for our Calculation;

• 2/3 = 4u - 5

To obtain the full length of the rope ;

• multiply both sides by 3/2

We have ;

2/3 * 3/2 = (4u -5) * 3/2

1 = 6u - 15/2

6u = 1 + 15/2

6u = 8.5

Hence, total length of rope expressed in terms of u is :

• 6u = 8.5
