On the number line above, points A, B, C, and D are integers, and AB: BC: CD = 3:2:1. What is the length of AC?
NeX [460]

Using proportions, it is found that the length of AC is of 15 units.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The ratios in this problem are given as follows:

  • \frac{AB}{BC} = \frac{3}{2}.
  • \frac{BC}{CD} = \frac{2}{1}.
  • \frac{AB}{CD} = \frac{3}{1}.

The entire length is of 18 units, AB is half of that, hence:

AB = 0.5 x 18 = 9 units.

BC is two thirds of the length from 6 to 15, hence:

BC = 2/3 x (15 - 6) = 6

Thus, the length of AC is:

AC = 9 + 6 = 15 units.

Help!<br> Find the value of x for which ABCD must be a parallelogram.
Stolb23 [73]
3
In a parallelogram, the diagonals (the lines inside from corner to corner) bisect each other. That means the two halves of the diagonal are equal to each other.
So
-9-6x=x-30
-9-6x+6x=x-30+6x
-9=7x-30
21=7x
x=3
