54 books make up 25% of the books in the library. How many books are there in the library.

Scrat [10]

25% is 1/4.

This means that 1/4 of the books in the library is 54, so just multiply 54 by 4, which gives you 100%, or all of the books. 54 times 4 is equal to 216, so there are 216 books in the library.

Hi!

solniwko [45]

Answer:

$y = 1x - 4$

Step-by-step explanation:

You have to solve for the x intercept on the equation

$2x-5y=8\\2x-5(0)=8\\2x=8\\x=4\\(4,0)$

That is the x intercept for that equation.

Then solve for the y intercept on the equation

$4x-3y=12\\4(0)-3y=12\\-3y=12\\y=-4\\(0,-4)$

That is the x intercept for that equation.

Use that to find slope for point slope form

$\frac{y_{2}-y_{1}}{x_{2}-_{1}} \\\\\frac{-4-0}{0-4} \\\\\frac{-4}{-4} \\\\1$

1 is the slope

and slope makes B the y intercept so the equation is

$y = 1x - 4$

Question in the image below:

horrorfan [7]

Answer:

x = 5/33 or 0.151515151

Step-by-step explanation:

7(-6x-2) = 8(3x-4)

step 1: simplify the equation.

-42x - 14 = 24x - 4

step 2: isolate the variable (using the balance method).

-42x - 14 + 14 = 24x - 4 + 14

-42x = 24x + 10

-42x - 24x = 24x - 24x + 10

-66x = 10

step 3: solve for x.

x = 10 ÷ -66

x = 5/33
