One line segment is 12 less than twice the length of another line segment. The sum of the links is 69 cm. How long are the lines segments?

Given:

Given that one line segment is 12 less than twice the length of another line segment.

The sum of the links is 69 cm.

Let x and y denote the lengths of two line segments.

Thus, we have;

and

We need to determine the lengths of the line segments.

Lengths of the line segments:

Let us use the substitution method to determine the length of the line segment.

Hence, substituting in the equation , we get;

Thus, the length of y is 27.

Substituting in the equation , we have;

Thus, the length of x is 42.

Therefore, the lengths of the line segments are 27 cm and 42 cm.

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
