The local library had a sale to get rid of the books that were slightly damaged it’s on paper back books for two dollars and har

kondor19780726 [428]

Answer:

The Local Library sold <u>31</u> hardcover books.

Step-by-step explanation:

Let number of paper back books be 'x'.

Let number of hardcover books be 'y'.

Given:

Total number of books sold = 89

Now Total number of books sold is equal to sum of number of paper back books and number of hardcover books.

framing in equation form we get;

$x+y=89 \ \ \ \ \ equation \ 1$

Now Given:

Cost of each paper back books = $2

Cost of each hardcover books = $5

Total Amount raised by library = $271

Now We know that Total Amount raised by library is equal to Cost of each paper back books multiplied by number of paper back books plus Cost of each hardcover books multiplied number of hardcover books.

framing in equation form we get;

$2x+5y=271 \ \ \ \ equation \ 2$

Now Multiplying equation 1 by 2 we get;

$2(x+y)=89\times2\\\\2x+2y = 178 \ \ \ \ equation \ 3$

Now Subtracting equation 3 from equation 2 we get;

$(2x+5y)-(2x+2y)=271-178\\\\2x+5y-2x-2y=93\\\\3y = 93\\\\y=\frac{93}{3}=31$

Substituting the value of y in equation 1 we get;

$x+y =89\\\\x+31=89\\\\x =89-31 = 58$

Hence The Local Library sold 58 paper back books and <u>31</u> hardcover books.

Help !! For a given input value x, the function g outputs a value y to satisfy the following equation.

otez555 [7]

Answer:

g(x)= 4x/5 + 8/5

Step-by-step explanation:

rewrite the equation as: -5y+2= -4x-6

move all terms not containing y to y=the right side of the equation

subtract 2 from both sides of the equation: -5y=-4x-6-2

subtract 2 from-6: -5y=-4x-8

divide each side by -5 and simplify: -5y=-4x-8 by -5

-5y÷-5 = -4x÷-5 + -8÷-5

now cancel the common factor of -5

divide y by 1: y= -4x/-5+ -8/-5

divide the negative to get the positives: y= (4)x/5 + -8/-5

y= 4x/5 +8/5

I hope this helped sorry if it wasn't what you were looking for.
