There are books in a library, there are 4 different kinds of books. Science books make up 3/4 of art books. Comic books are 1/4

Sergeeva-Olga [200]

Answer:

The total number of books is 1020.

Step-by-step explanation:

Denote the books by their first letter.

From the provided information:

$S=\frac{3}{4}A$
$C=\frac{1}{4}T$
$H=\frac{1}{5}T$
$H = A-80$

Compute the expression of T as follows:

$H = A-80\\\\\frac{1}{5}T=A-80\\\\T=5A-400...(i)$

Compute the value of C in terms of A:

$C=\frac{1}{4}T\\\\C=\frac{1}{4}\times {5A-400}\\\\C=\frac{5}{4}A-100...(ii)$

Compute the value of A as follows:

Use expressions (i) and (ii):

$T=S+C+H+A\\\\5A-400=\frac{3}{4}A+\frac{5}{4}A-100+A-80+A\\\\5A-400=4A-180\\\\A=220$

Compute the value of T as follows:

$T=5A-80\\\\T=(5\times 220)-80\\\\T=1100-80\\\\T=1020$

Thus, the total number of books is 1020.

Hi my lil bunny!

❀ _____.______❀_______._____ ❀

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

$(\frac{2}{3}x) ( \frac{-6}{7} + \frac{4}{5}) = [\frac{\frac{2^x4}{3} }{5} ] ( \frac{-6}{7} )$

$\frac{-4}{105} x = \frac{-4x^5}{35}$

Step 1: Subtract $(-4)/35x^5$ from both sides.

$\frac{-4}{105} x - \frac{-4}{35x^5} = \frac{-4x^5}{35} - \frac{-4x^5}{35}\\\\\frac{4}{35}x^5 + \frac{-4}{105} = 0$

Step 2: Factor left side of equation.

$x(0.114286 x^4 - 0.038095 ) = 0$

Step 3: Set factors equal to 0.

$x = 0 or 0.114286 x^4 - 0.038095 = 0\\\\x = 0 or x = -0.759836 or x = 0.759836$

So the answer is : x = 0 or x = - 0.759836 or x = 0.759836
