Answer:

x=-1/7

Step-by-step explanation:

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

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

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

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

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

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

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

$-10x+1=-3x$

$-7x=1$

$x=-1/7$

Answer:

B. 300

Step-by-step explanation:

Final figure volume = big cuboid volume - small cuboid volume

Volume of a cuboid = height x width x length

Final figure = (6 x 6 x 15) - (4 x 4 x 15)

Final figure = 540 - 240

Final figure = 300mm^2

What is the next letter b a d e h g k

aivan3 [116]

Abcdefghijklmnopqrstuvwxyz

ok

b to a
goes back 1 letter

then b to d
skips 3 letters forward

then d to e
1 forward

e to h
skips 3 forward

h to g
goes 1 back

g to k
goes 3 forward

pattern seems to be
1back, 3 forward, 1 forward, 3 forward, repeat
so we are at 3 forward after than 1 back, so the next one is 1 forward

1 forward from k is l

the next letter is L
