PLEASE HELP
find the value of x !

Answer:

Step-by-step explanation:

x - an integer

2x - an even integer (the first)

Even integers increase by 1 so:

2x+2   - next consecutive integer (the second)

3(2x+2) - three times the second

2x+4  - the third consecutive integer

2x+2x+4 -  the sum of the first and third

2x+2x+4+18 -  the sum of the first and third increased by 18

2x+2x+4+18 = 3(2x+2)  

4x + 22 = 6x + 6

      -6        -6

4x + 16  = 6x

     -4x      -4x

       16 = 2x

2x = 16

2x+2 = 18  

2x+4 = 20

Check:  16+20+18=54;   3×18=54

Answer:

n ÷ (2 - 3) ≤ 2

Step-by-step explanation:

Let n be 'the number'

n is divided by 3 less than 2

n ÷ (2 - 3) is at most 2

Answer:

x = -4 2/13

x = -4.15384615385

x = -54/13

(they are all the same, just in different formats)

Step-by-step explanation:

(5/3x) + 6 = (2/9)x

first, make all "x"s have a common denominator

(5/3) = (15/9)

so

(5/3)x = (15/9)x

(15/9)x + 6 = (2/9)x

solve using inverse operations

(15/9)x + 6 = (2/9)x

-(2/9)x         -(2/9)x

(13/9)x + 6 = 0

            -6    -6

(13/9)x = -6

to get rid of the fraction, multiply the entire equation by the denominator

(13/9)x = -6

*9          *9

13x = -54

/13     /13

x = -4 2/13

x = -4.15384615385

x = -54/13

Answer:

4/6 is the answer

Step-by-step explanation:

You'll make equivalent fractions by multiplying or dividing both top and bottom by the same amount. You only multiply or divide, never add or subtract, to get an equivalent fraction. Only divide when the top and bottom stay as whole numbers.

Answer:

$65.325 or $65.33

Step-by-step explanation:

When looking for a percentage in a number, you want to multiply that number by the percentage. Remember that all percentages are to the hundreth power, or 0.00. So if you want to find 30% of 50.25, you multiply it by 0.30 or 0.3. After calculating that you will come up with 15.075 as the percentage. Since the store is marking the price up, you add it to the original price. So your equation is 50.25 + 15.075 =?. After calculating that, you get the answer 65.325. That is only half of your answer though because, when dealing with money, you always round to the nearest hundredth. So when you round 65.325, you get 65.33 which should be the correct answer.

Answer:

x = 4, x ≠ -1

Step-by-step explanation:

√3x + 4 = x

(√3x + 4)² = x² (Square both sides to get rid of the radical.)

3x + 4 = x²

0 = x² - 3x - 4 (Set everything to 0 by moving everything to one side.)

0 = (x - 4)(x + 1) (Factor.)

x = 4   x = -1

Now we need to check for extraneous solutions:

√3(4) + 4 = 4

√12 + 4 = 4

√16 = 4

4 = 4

√3(-1) + 4 = -1

√-3 +4 = -1

√1 = -1

1 ≠ -1

-1 is an extraneous solution.

[tex]\boxed {12x + 2}[/tex]

Step-by-step explanation:

Solve the following expression:

[tex]4(3x + 2) - 6[/tex]

-Use Distributive Property:

[tex]4(3x + 2) - 6[/tex]

[tex]12x + 8 - 6[/tex]

-Combine like terms:

[tex]12x + 8 - 6[/tex]

[tex]\boxed {12x + 2}[/tex]

Answer:

[tex]12x+2[/tex]

Step-by-step explanation:

The first step is to distribute the 4 to the parenthesis. This turns the equation into:

[tex](12x+8)-6[/tex]

We can remove the parenthesis now. Also, now we combine like terms. There are no other variables in the equation, so we leave the 12x alone. Combine the +8 and the -6 to get +2. This leaves the equation at:

[tex]12x+2[/tex]

Step-by-step explanation:

the integer that represents the total charge of 7 electrons is -1.The total charge of electrons is given by the formula:

total charge = number of electrons x charge of each electron

what are electrons ?

Electrons are subatomic particles that carry a negative electric charge. They are one of the fundamental particles that make up atoms, along with protons and neutrons. Electrons are found in shells or energy levels that surround the atomic nucleus

In the given question,

The total charge of electrons is given by the formula:

total charge = number of electrons x charge of each electron

The charge of an electron is a fundamental constant, which is equal to -1.602 x 10⁻¹⁹ Coulombs. Therefore, the total charge of 7 electrons can be calculated as:

total charge = 7 x (-1.602 x 10⁻¹⁹) C

total charge = -1.1214 x 10⁻¹⁸ C

Note that the charge of an electron is negative because it has an opposite charge to the positively charged protons in an atom. Therefore, the total charge of 7 electrons is also negative. To express this charge as an integer, we need to convert it to scientific notation and round to the nearest whole number. Rounding to the nearest whole number gives:

total charge = -1 x 10⁻¹⁸ C

Therefore, the integer that represents the total charge of 7 electrons is -1.

Step-by-step explanation:

Answer:

Ryan gave 16 cards to Josiah.

Step-by-step explanation:

First we will divide 36 by 9.

36/9 = 4

We know that 1/9 of 36 is 4.

1/9 + 1/9 + 1/9 + 1/9 = ?

4 + 4 + 4+ 4 = ?

4 * 4 = 16

4/9= 16
