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

Is (2,2) a solution of the inequality y≤3x-5?

$\blue{\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}$

Simply write the y-coordinate in lieu of y and write the x-coordinate in lieu of x:-

2≤3(2)-5

Multiply:-

2≤6-5

2≤1

2 <em>is </em>less than 1, but it's not equal to 1.

So the right option is:-

$\bigcirc\!\!\!\!\!\bigstar$ (2,2) would be a solution if the inequality was y<3x-5

Answer:

Final answer is $W=\frac{CL}{100}$ .

Step-by-step explanation:

Given equation is $C=\frac{100W}{L}$ .

Now we need to solve the given equation $C=\frac{100W}{L}$ for indicated variable W.

That means we need to isolate W. In other words move 100 and L to the right side of the equation.

$C=\frac{100W}{L}$

$CL=100W$

$\frac{CL}{100}=W$

$W=\frac{CL}{100}$

Hence final answer is $W=\frac{CL}{100}$ .
