I need to find the value of x and BC if B is between C and D<br><br> CB=4X-9, BD= 3X+5, and CD = 17
Rainbow [258]

It is given in the question that B is in between C and D.

Therefore

CB+ BD = CD

Substituting the given values of CB,BD and CD, we will get

4x-9+3x+5=17

Combining like terms, we will get

7x-4=17

Now we need to move 4 to the right side by adding 4 to both sides, that is

7x = 21&#10;\\&#10;x=3

Then...
1.20 - .965= .235
So...
The fourth board has the width of .235 cm.
