Answer and Step-by-step explanation:

8a.

3x + 6 = 27

<u>Subtract 6 from both sides.</u>

3x = 21

<u>Divide 3 from both sides.</u>

<u>x = 7</u>

<u></u>

<u></u>

8b.

6x + 3 = 27

<u>Subtract 3 from both sides.</u>

6x = 24

<u>Divide 6 from both sides.</u>

<u>x = 4</u>

<u></u>

<u></u>

8c.

27x + 3 = 6

<u>Subtract 3 from both sides.</u>

27x = 3

<u>Divide 27 from both sides.</u>

x = 3/27

<u>Simplify the fraction</u>

<u>x = 1/9</u>

<u></u>

9.

The above steps are the reasonings for the above answers.

Answer:

x=7

x=4

x=1/9

Step-by-step explanation:

For number 9 you can either type out the work or say something like:

To solve all of the problems in Question 8 I had to move all of the terms without an (x) to the right side. After I did this I divided everything by the number attached to the (x) to find the value of (x) by itself.

the length , breadth and height of a cuboid is 2x^2y cm,5y^2z cm and 4z^2x cm. The volume of the cuboid is ...............
kondor19780726 [428]

For this case we have that by definition, the volume of a cuboid is given by:

V = L * A * h

Where:

L: It's the long

A: It is the width

h: It is the height

According to the problem data we have:

L = 2x ^ 2y \ cm\\A = 5y ^ 2z \ cm\\h = 4z ^ 2x \ cm

So, the volume of the cuboid is:

V = (2x ^ 2y) (5y ^ 2z) (4z ^ 2x)\\V = 10x ^ 2y ^ 3z (4z ^ 2x)\\V = 40x ^ 3y ^ 3z ^ 3

Finally, the volume of the cuboid is: V = 40x ^ 3y ^ 3z ^ 3

Answer:

V = 40x ^ 3y ^ 3z ^ 3

PLEASE HELP! (1/4) - 50 POINTS -
Annette [7]

Answer:

  D)  0.35

Step-by-step explanation:

The table gives the area between z=0 and the given magnitude of z. That is, the area between z = 0 and z = -0.6 is 0.23, as found in the 0.6 column of the table. Similarly, the area between z = 0 and z = 0.3 is 0.12, as found in the 0.3 column of the table.

The area between z = -0.6 and z = +0.3 is the sum of these areas:

  p(-.6<z<.3) = 0.23 +0.12 = 0.35
