4x = -36
x = -36/4
x = - 9
================
5x - 15 = 50
5x = 50 + 15
5x = 65
x = 65/5
x = 13
================
4(x + 2) - 17 = 35
4x + 8 = 35 + 17
4x = 44
x = 44/4
x = 11
=================
6x + 12 = 4x - 18
6x - 4x = -18 - 12
2x = - 30
x = -30/2
x = -15
==================
1/2(4x - 10) + 5 = x - 11
2x - 5 + 5 = x - 11
2x - x = -11
x = -11
=================
Have a good day :)

If 3 marbles are drawn from a bag of 12 marbles consisting of three red, four white and five blue, without returning them to the
FinnZ [79.3K]

Answer:

The probability of that happening is 1/22

Step-by-step explanation:

In order to find the probability, you need to start by finding the probability for each step. The probability of the first one being red is the number of red marbles divided by the total number of marbles.

3 red / 12 total.

3/12

1/4

Now the chance that the second is white is the total number of white marbles divided by how many are left in the bag.

4 white / 11 left

4/11

Lastly, the chance of the last one being blue is the number of blue marbles divided by the amount of total marbles left after two pulls.

5 blue/ 10 left

5/10

1/2

Now to find the overall probability of all 3 happening, we multiply all 3 probabilities together.

1/4 * 4/11 * 1/2 = 1/22

Y = 3x-2 estimate the value of x when y=3
jok3333 [9.3K]

Answer:

x = 5/3

General Formulas and Concepts:
<u>Algebra I</u>

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify given.</em>

y = 3x - 2

y = 3

<u>Step 2: Solve for </u><u><em>x</em></u>

  1. [Equation] Substitute in <em>y</em>:
    3 = 3x - 2
  2. [Addition Property of Equality] Add 2 on both sides:
    5 = 3x
  3. [Division Property of Equality] Divide 3 on both sides:
    5/3 = x
  4. Rewrite:
    x = 5/3

∴ the value of <em>x</em> when <em>y</em> = 3 is equal to 5/3, or approximately 1.67.
