Sophia had 64¢ until she spent 1 quarter. How much money does Sophia have now?

aleksklad [387]

Answer:

Sophia now has 39 cents.

Step-by-step explanation:

One quarter = 25 cents

Since Sophia had 64 cents until she spent 25 cents (1 quarter).

So we subtract 25 cents from 64 cents.

$\: \: \: 64 \: cents \\ \frac{ - 25 \: cents}{ \: \: \: 39 \: cents}$

Therefore, Sophia now has 39 cents.

What is the LCD of the following rational expressions?

Aloiza [94]

$\dfrac{x}{x+1} \ , \ \dfrac{7x}{x-1}$

$\dfrac{x (x -1)}{(x+1)(x -1)} \ , \ \dfrac{7x(x+1)}{(x-1)(x+ 1)}$

We know that (a + b)(a - b) = a² - b²:

$\dfrac{x (x -1)}{x^2 - 1}} \ , \ \dfrac{7x(x+1)} {x^2 - 1}$

Answer: LCD = ( x + 1) (x - 1)
