Answer:

x=10/3

Step-by-step explanation:

8x-2-5x=8

then you group like terms=

8x-5x-2=8

add similar elements

3x-2=8

Add 2 to both sides

3x-2+2=8+2

Then lastly divide both sides by 3

3x/3=10/3

And you get 10/3

A rectangular prism has a length of 1 2 in, a width of 2 in, and a height of 3 1 2 in. (a) How many cubes with side lengths of 1

erma4kov [3.2K]

V of rectangular prism = l * w * h = 12 * 2 * 312 = 7,488 in³
V of one cube with side lengths 12 = l * w * h = 12 * 12 * 12 = 1,728 in³

Divide the volume of rectangular prism by the volume of the cube.

7488 / 1728 = 13 / 3 or 4.3. . .

The angles 3x+6 and 5x + 6 are supplements. What are the two angles

yarga [219]

Answer:

x = 21

Step-by-step explanation:

Step 1: Make an expression

Since they are supplements, that means that they add up to 180 degrees.

3x + 6 + 5x + 6 = 180

Step 2: Combine like terms

3x + 6 + 5x + 6 = 180

(3x + 5x) + (6 + 6) = 180

8x + 12 = 180

Step 3: Subtract 12 from both sides

8x + 12 - 12 = 180 - 12

8x = 168

Step 4: Divide both sides by 8

8x / 8 = 168 / 8

x = 21

Answer: x = 21
