Question

B is the midpoint of AC and D is the midpoint of CE solve for X given BD equals 3X +5 and 80 equals 4X +20?

Answer 1

Answer: The value of BD will be 50 units.

Step-by-step explanation:

Since we given that

B is the midpoint of AC and D is the midpoint of CE .

and

$BD=3x+5\\\\4x+20=80$

Now, we will use the second equation, we get

$4x+20=80\\\\4x=80-20\\\\4x=60\\\\x=\frac{60}{4}\\\\x=15$

So, BD will be

$3x+5\\\\=3(15)+5\\\\=45+5\\\\=50$

Hence, the value of BD will be 50 units.
