Answer:

x = 1/10

Step-by-step explanation:

2/x -2 = 3/2x +3

Add 2 to each side

2/x -2+2 = 3/2x +3+2

2/x = 3 /2x +5

Subtract 3/2x from each side

2/x -3/2x = 3 /2x - 3/2x +5

2/x - 3/2x = 5

Get a common denominator

2/x *2/2 -3/2x =5

4/2x - 3/2x = 5

1/2x =5

Multiply each side by 2x

1 /2x * 2x = 5 *2x

1 = 10x

Divide each side by 10

1/10 = 10x/10

1/10 =x

The carpet for the office you completed cost $576. If you're using the same carpet in the new client's bedroom, how much will it

Licemer1 [7]

The cost of similar carpet in the client's bedroom is $225

<h3>
Area of Shapes</h3><h3 />

Given Data

Cost of Carpet = $576

Area of Office = 16*19.2 = 307.2 square feet

Area of Bedroom = 12*10 = 120 square feet

if 307.2 square feet of carpet will cost $576

the 120 square feet of carpet will cost $x

cross multiplying we have

x = 120*576/307.2

x = 69120/307.2

x = $225

A circus tent is cylindrical up to a height of 7 m and is in the shape of a cone over it, the diameter of the cylindrical part i

yan [13]

$\bold{\huge{\underline{ Solution }}}$

<h3>Given :- </h3>

• The circus tent is composed of cylinder and a cone.

• The height and diameter of the cylindrical part are 7m and 10m

• The total height of the circus tent 19m

• The cost of making the tent at a cost of 35 m² cloth.

<h3>Let's Begin :- </h3>

Here, we have ,

Cylinder and cone
The height and diameter of the cylinder are 7m and 10m
Therefore , radius = 5 m

We know that, 

Curved Surface area of the cylinder

$\sf{ = 2{\pi}rh}$

Subsitute the required values,

$\sf{ = 2{\times}3.14{\times}5{\times}7}$

$\sf{ = 6.28 {\times}5{\times}7}$

$\sf{ = 6.28 {\times}35}$

$\bold{ = 219.8m^{2}}$

Thus, The area of the cylinder is 219.8m² .

•We have to find the area of the cone.

•Here, Base of cone = diameter of the cylinder.

•The height of the cone will be

= Height of the tent - Height of cylinder

$\sf{ = 19 - 7 }$

$\bold{ = 12 m }$

We know that, 

Area of cone

$\bold{ = {\pi}rl }$

Here, l is the slant height.

Slant height of the cone

$\sf{ = \sqrt{ h^{2} + r^{2}} }$

$\sf{ = \sqrt{ (12)^{2} + (5)^{2}} }$

$\sf{ = \sqrt{ 144 + 25}}$

$\sf{ = \sqrt{ 169}}$

$\sf{ = \sqrt{ 13{\times} 13 }}$

$\bold{ = 13 m }$

Thus, The slant height of the cone is 13 m

Subsitute the required values in the above formula

$\sf{ = 3.14 {\times} 5 {\times} 13}$

$\sf{ = 3.14 {\times} 65}$

$\bold{ = 204.1 m^{2}}$

Thus, The area of the cone is 204.1 m² .

<h3>Therefore ,</h3>

The total area of the circus tent

$\sf{ = 204.1 + 219.8}$

$\bold{ = 423.9m^{2} \: or \: 424 m^{2}}$

We have to find the total cost of making the tent.
The cost for 1 m² = 35

Therefore,

The total cost for making the circus tent

$\sf{ = 424 {\times} 35}$

$\bold{ = 14840}$

Hence, The total cost for making the tent is 14840 .
