The manager at Gabriela's Furniture Store is trying to figure out how much to charge for a book shelf that just arrived. The boo
Burka [1]

Answer: The manager sold the book shelf at $235.2

Step-by-step explanation:

Since we have given that

Wholesale price of the book shelf = $147.00

But Gabriela's Furniture Store marks up all furniture by 60%.

So, Mark up value is given by

\frac{60}{100}\times 147\\\\=\frac{8820}{100}\\\\=\$88.2

So, the new price that the manager sold the book shelf is given by

147+88.2\\\\=\$235.2

Hence, the manager sold the book shelf at $235.2

8x=4x^2-1 <br>solve by completing the square
Klio2033 [76]
Get the x terms by themselves on one side and a constant on the other side of the equal sign...

4x^2-8x=1  make the leading coefficient equal to one...

x^2-2x=1/4  now halve the linear coefficient, -2 in this case, square it, and add that value to both sides of the equation...-2/2=-1, -1^2=1 so

x^2-2x+1=1+1/4

x^2-2x+1=5/4  now the left side is a perfect square...

(x-1)^2=5/4  take the square root of both sides...

x-1=±√(5/4)  add 1 to both sides

x=1±√(5/4)

The equation which represents x, the width of the border is 2 left-bracket (12 + 2 x) + (15 + 2 x) right-bracket = 74. What is t
bulgar [2K]

Answer:

2 1/2

Step-by-step explanation:

If you do the step by step calculation:

Step 1: Simplify both sides of the equation.

2(12+2x+15+2x)=74

(2)(12)+(2)(2x)+(2)(15)+(2)(2x)=74(Distribute)

24+4x+30+4x=74

(4x+4x)+(24+30)=74(Combine Like Terms)

8x+54=74

8x+54=74

Step 2: Subtract 54 from both sides.

8x+54−54=74−54

8x=20

Step 3: Divide both sides by 8.

8x divide by 8 and that is 20 divided by 8

leaves you with the answer 5/2.

If you then turn the improper fraction into a mixed fraction you get 2 and one half.

Answer= 2 1/2 or "a" <u>DEPENDS ON WHAT QUIZ YOU HAVE</u>

Peace!
