almost right

400 1000

____ = _____ now you cross multiply to solve (cross products

14 x

400 times x = 14 times 1000

400x = 14000 now divide both sides by 400

400 400

x = 35

Add and simplify the result, if possible. x/18 + 3/18

Slav-nsk [51]

$\frac{x}{18}$ and $\frac{3}{18}$ both have a common denominator, so you can combine them into a single fraction:

$\frac{x}{18}+\frac{3}{18}=\frac{x+3}{18}$

You cannot simplify this fraction further:

- - - - - - - - - - - - - - - - - - - -

Answer:

$\boxed{\frac{x+3}{18}}$

- - - - - - - - - - - - - - - - - - - - -

Which shows the expressions rewritten with the least common denominator?

baherus [9]

Answer:

D. (14x-4)/(8x^2) and (x^2-x)/(8x^2)

Step-by-step explanation:

The least common denominator will be 8x^2, the product of 2 and x to the highest of their powers in either of the denominators.

$\left\{\dfrac{7x-2}{4x^2},\ \dfrac{x-1}{8x}\right\}=\left\{\dfrac{7x-2}{4x^2}\cdot\dfrac{2}{2},\ \dfrac{x-1}{8x}\cdot\dfrac{x}{x}\right\}\\\\=\left\{\dfrac{14x-4}{8x^2},\ \dfrac{x^2-x}{8x^2}\right\}$
