Answer:

4=x

Step-by-step explanation:

1/5( 2x+92) = 5x

Multiply each side by 5

5*1/5( 2x+92) = 5x*5

( 2x+92) = 25x

Subtract 2x from each side

2x+92-2x = 25x-2x

92 = 23x

Divide by 23

92/23 = 23x/23

4=x

Answer:

x = 4

Step-by-step explanation:

1/5 ( 2x + 92 ) = 5x

\small \sf \frac{1}{5} ×  ( 2x + 92 ) = 5x \\

distribute 1/5 through the parantheses

\small \sf \frac{2}{5}x +  \frac{92}{5} = 5x \\

multiply both side of equation by 5

\small \sf \frac{2}{5}x \times 5 +  \frac{92}{5} \times 5 = 5x  \times 5\\

  • 2x + 92 = 25x

Move all variables to the left hand side and change their sign

  • 2x + 92 - 25x = 0

combine like terms

  • 2x - 25x + 92 = 0

calculate

  • -23x + 92 = 0

Move all the constant to the right side and change their sign

  • -23 x = - 92

divide both side by -23x

  • -23x / -23 = -92/-23
  • x = 4

An office room is 12 ft by 10 ft with a door that is 30 inches wide. How many feet of baseboard are needed to go around the room
Lina20 [59]
Draw a diagram to illustrate the problem as shown below.
The length of baseboard needed is AB + BC + CD + DE + FE.
Note that 30 in = 30/12 ft = 2.5 ft.

Because of the door opening,
AB + EF = 12 - 2.5 = 9.5 ft
Also,
BC = DE = 10 ft
CD = 12 ft.

The amount of baseboard needed is
AB + BC + CD + DE + FE
= (AB + EF) + BC + CD + DE
= 9.5 + 10 + 12 + 10
= 41.5 ft

Answer:
41.5 feet of baseboard.

alexandr1967 [171]
The answer is false.

For a square pyramid, the volume is calculated by 1/3*B*h. The height should touch the tip and lie perpendicular to the base. Slant height is used for surface area, not volume.
