a p e x

Answer 2

Hello!

The answer is:

The value of x is 3.9 units.

Why?

From the statement we know that the sum of the distances AB and BC is equal to 9.7 units, so, we need to write one equation to create a relation between the given distances and the total distance (AB + BC)

So, writing the equation, we have:

`AB+BC=AC\\\\2x-3+(x+1)=9.7`

Now, adding like terms, we have:

`2x-3+(x+1)=9.7`

`2x+x-3+1=9.7`

`3x-2=9.7`

`3x=9.7+2`

`x=(9.7+2)/(3)=(11.7)/(3)=39.9`

Hence, we have the value of x is 3.9 units.

Have a nice day!
