Answer:

x is greater than -2 and less than or equal to 3

Step-by-step explanation:

so the 3x + 1 is greater than -5

so 3x is greater than -6

we divide both sides by 3

then we find out that x is greater than -2

we also know that 3x + 1 is less than or equal to 10

so 3x is less than or equal to 9

we divide both sides by 3

then we find out that x is less or equal to 3

so we can say that x is greater than -2 and less than or equal to 3

The floor plan shows an l shaped room. Shane wants to buy carpet for the room. The cost for one square foot of carpet is $4. Wha
VashaNatasha [74]

The area of shape is the amount of space on it.

The cost to carpet the room is $224

From the floor plan (see attachment), we can divide the room into two shapes:

  1. <em>A 8ft by 6ft rectangle</em>
  2. <em>A 4ft by 2ft rectangle</em>

<em />

So, the area of the floor plan is:

\mathbf{Area = 8ft \times 6ft + 4ft \times 2ft}

\mathbf{Area = 48ft^2 + 8ft^2}

\mathbf{Area = 56ft^2}

The unit cost of carpet is <em>$4 per one square foot </em>

So, the cost to carpet the room is:

\mathbf{Cost = \$4 \times 56}

\mathbf{Cost = \$224}

Hence, the cost to carpet the room is $224

How many 1-inch cubes do you need to create a cube with an edge length of 5 inches?
Kruka [31]
Number of 1 inch cubes:

Volume of the 1 inch cubes = 1*1*1 = 1 cubic inches.

Volume of the 5 inch cubes =  5*5*5 = 125 cubic inches.

Number =  Volume of the 5 inch cubes / Volume of the 1 inch cubes

            =  125 /1 = 125.

125 of the 1-inch cubes.
