Answer:

x=-1/7

Step-by-step explanation:

$\frac{3x-1}{3} -\frac{2x}{x-1} =x$

$\frac{(3x-1)(x-1)}{3x-3} -\frac{2x(3)}{3x-3} =x$

$\frac{3x^2-4x+1}{3x-3} -\frac{6x}{3x-3} =x$

$\frac{3x^2-10x+1}{3x-3} =x$

$\frac{3x^2-10x+1}{3x-3} =\frac{x(3x-3)}{3x-3}$

$\frac{3x^2-10x+1}{3x-3} =\frac{3x^2-3x}{3x-3}$

$3x^2-10x+1=3x^2-3x$

$-10x+1=-3x$

$-7x=1$

$x=-1/7$

What is the value of n?<br><br><br><br> n–2=10n+42

Bingel [31]

Answer:

N= -44/9 Hope this helped, <3

Step-by-step explanation:

Let's solve your equation step-by-step.

n−2=10n+42

Step 1: Subtract 10n from both sides.

n−2−10n=10n+42−10n

−9n−2=42

Step 2: Add 2 to both sides.

−9n−2+2=42+2

−9n=44

Step 3: Divide both sides by -9.

Answer:

x ≈ 3.1 ft

Step-by-step explanation:

The segment from the centre to the chord is a perpendicular bisector, thus

The triangle is right with base = $\frac{1}{2}$ x

Applying Pythagoras' identity to the right triangle, then

( $\frac{1}{2}$ x )² + 1.4² = 2.1²

$\frac{1}{4}$ x² + 1.96 = 4.41 ( subtract 1.96 from both sides )

$\frac{1}{4}$ x² = 2.45 ( multiply both sides by 4 )

x² = 9.8 ( take the square root of both sides )

x = $\sqrt{9.8}$ ≈ 3.1 ft ( to the nearest tenth )
