Answer:

-5=n

Step-by-step explanation:

75=3(-6n-5)

Distribute the 3

75=-18n-15

Add 15 to both sides

90=-18n

Divide both sides by -18 to get n alone

-5=n

In the figure below, B is between A and C, and C is between B and D. If AC=9, BD=10, and BC-2, find AD
ehidna [41]

Considering the situation described in the problem, the length of segment AD is of: 17 units.

<h3>How to find the length of segment AD?</h3>

From the situation described in the problem, segment AD is divided into three parts:

  • Part AB.
  • Part BC.
  • Part CD.

Then, the length of segment AD is:

AD = AB + BC + CD.

We have that AC = 9, hence:

AB + BC = 9.

We also have that BD = 10, then:

BC + CD = 10.

Since BC = 2, we have that:

  • AB + BC = 9 -> AB + 2 = 9 -> AB = 7.
  • BC + CD = 10 -> 2 + CD = 10 -> CD = 8.

Then the length of segment AD is given as follows:

AD = AB + BC + CD = 7 + 2 + 8 = 17.
