Answer:

The number at B is 10.6

Step-by-step explanation:

Let the number at B be x.

We know that distance between two points on the number line is the absolute value of the difference of numbers at those points.

Then distances representing the lengths of segments AB and BC are:

AB = x - 9
BC = 13 - x

We are given the ratio of segments:

AB/BC = 2/3

Substitute and solve for x:

(x - 9)/(13 - x) = 2/3
3(x - 9) = 2(13 - x)
3x - 27 = 26 - 2x
3x + 2x = 26 + 27
5x = 53
x = 53/5
x = 10.6

5/x+3 take away 1/x-2 equals to 1. solve two possible answers for x

satela [25.4K]

Answer:

<h3><u>Solution</u><u>:</u><u>-</u></h3>

First write the given equation

$\qquad{:}\longrightarrow$ $\sf \dfrac {5}{x+3}-\dfrac{1}{x-2}=1$

$\qquad{:}\longrightarrow$ $\sf \dfrac {5 (x-2)-1 (x+3)}{(x+3)(x-2)}=1$

$\qquad{:}\longrightarrow$ $\sf \dfrac {5x-10-x }{x^2-6x-6} =1$

use cross multiplication method

$\qquad{:}\longrightarrow$ $\sf 5x-x-10=x^2-6x-6$

$\qquad{:}\longrightarrow$ $\sf x^2-6x-6=4x-10$

$\qquad{:}\longrightarrow$ $\sf x^2-6x-4x-6+10=0$

$\qquad{:}\longrightarrow$ $\sf x^2-10x+4=0$

use quadratic formula

$\qquad{:}\longrightarrow$ $\sf x=\dfrac {-b\underline{+}\sqrt {b^2-4ac}}{2a}$

$\qquad{:}\longrightarrow$ $\sf x=\dfrac {10\underline{+}\sqrt {(-10)^2-4×1×4}}{2×1}$

$\qquad{:}\longrightarrow$ $\sf x=\dfrac {10\underline{+}\sqrt{100-16}}{2}$

$\qquad{:}\longrightarrow$ $\sf x=\dfrac {10\underline{+}\sqrt {84}}{2}$

$\qquad{:}\longrightarrow$ $\sf x=\dfrac {10+\sqrt {84}}{2}\quad or\quad x=\dfrac {10-\sqrt{84}}{2}$
