A wholesaler purchased a certain number of books for $864. If the price per book was $3 less, the number of the books that could

Goshia [24]

Answer:

$27

Step-by-step explanation:

b will be the number of books and p will be the price, now we just use a system of equations

bp = 864

b=864/p

(b+4)(p-3) = 864

(864/p +4)(p-3) = 864

864 - 2592/p + 4p -12 = 864

864p - 2592 + 4p^2 -12p - 864p = 0

4p^2 -12p -2592 = 0

4(p^2 - 3p -648) = 0

4((p - 3/2)^2 - 2601/4) = 0 (completed the square here)

4(p - 3/2)^2 -2601 = 0

p = +/-51/2+3/2

p = 27 or -24

A negative price doesn't make sense so it's 27, now we go back to the other equation if you want to find the number of books.

b=864/p

b = 864/27

b = 32

Mike is cycling from the library to his home. The equation shows Mike's distance (y), in miles, from his home after x minutes: y

MakcuM [25]

"12" represents Mike's original distance from his home. As he rides, this distance decreases by 2 miles/minute (which is rather unlikely, as that'd be 120 mph).

How would you write the following expression as a sum or difference? `"log"(root(3)(2 - x)/(3x))`

pashok25 [27]

<h3>Further explanation</h3>

Let's recall following formula about Exponents and Surds:

$\boxed { \sqrt { x } = x ^ { \frac{1}{2} } }$

$\boxed { (a ^ b) ^ c = a ^ { b . c } }$

$\boxed {a ^ b \div a ^ c = a ^ { b - c } }$

$\boxed {\log a + \log b = \log (a \times b) }$

$\boxed {\log a - \log b = \log (a \div b) }$

<em>Let us tackle the problem!</em>

$\texttt{ }$

$\log \frac{\sqrt{3}(2-x)}{(3x)} = \log \sqrt{3} + \log (2-x) - \log (3x)$

$\log \frac{\sqrt{3}(2-x)}{(3x)} = \log 3^{1/2} + \log (2-x) - (\log 3 + \log x)$

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

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