Answer:
BD measures 20 units.
Step-by-step explanation:
We are given that Point C is on the line segment BD, where:
And we want to determine the numerical length of BD.
Since C is somewhere on BD, BD is the sum of BC and CD:
Substitute:
Solve for <em>x</em>. Subtract:
Hence, the value of <em>x</em> is 4.
BD is given by 5<em>x</em>. Therefore:
In conclusion, BD measures 20 units.
When you solve a proportion, your first step should be to cross-multiply.
= 
When you cross-multiply, you should get this equation:
(2x)(3) = (x + 3)(5)
Now, solve it using algebra.
(2x)(3) = (x + 3)(5) Multiply
6x = 5x + 15 Subtract 5x from both sides
x = 15
The value of x is 15.
