I Need with help with 55

Answer:

3(2x-3)

Step-by-step explanation:

6x-9 Common factor is 3

6x/3 = 2x

-9/3 = -3

3(2x - 3)

Steps to solve:

3(3x - 6) = 18

~Distribute left side

9x - 18 = 18

~Add 18 to both sides

9x = 36

~Divide 9 to both sides

x = 4

Best of Luck!

Answer:

x = 4

Step-by-step explanation:

Let's work on isolating (3x - 6).  Start by dividing both sides of 3(3x - 6) = 18 by 3, obtaining:

3x - 6 = 6.

Next, add 6 to both sides:

3x = 12

Finally, divide both sides by 3:

x = 4

The ratio of monthly income to the savings in a family is 5 : 4 If the savings be $9000, find the income and the expenses.

2. What should be added to the ratio 5 : 11, so that the ratio becomes 3 : 4?

3. Two numbers are in the ratio 7 : 5. If 2 is subtracted from each of them, the ratio becomes 3 : 2. Find the numbers.

4. Two numbers are in the ratio 3 : 7. If their sum is 710, find the numbers.

=====================================================

Explanation:

We're given the following

[tex]C = \{ x | x \in \mathbb{N}, \ 30 < x < 56, \ \text{ x is divisible by 6}\}[/tex]

which means that we have a set of natural numbers between 30 and 56, excluding both endpoints, and the set of numbers are also multiples of 6.

So looking at the multiples of 6 that are between 30 and 56 leads us to

{30, 36, 42, 48, 54}

but we cross off 30 as we want x to be larger than that, so we get this updated final list

{36, 42, 48, 54}

There are four items in this final list so the cardinality of the set described is 4. The cardinality is just the number of items in a given set.

Answer:

Since we get '2' as an output when we input '0'

So, the function must be increasing the value of x by 2

We see that happen in the second case as well, as our input is incremented by 2

Hence, we can say that

f(x) = x + 2

Step-by-step explanation:

First of all, less than is the sign that points to the left,

Secondly, I'm guessing that y is actually V,

Before Ray gave Jan cards, she had 18,

so it is 18 plus V (the number of cards Ray gave her),

Answer:

a = - 1.1

Step-by-step explanation:

The condition for a single variable function f(x) to be decreasing is f'(x) < 0.

f(x) = 4/x^2 - 6x + 9

Then, differentiating with respect to x on both sides we get,

f(x) = 4(-2)(1/x^3) - 6 < 0

-8/x^3  - 6 < 0

8/x^3 + 6 > 0

{Dividing both sides with - 1 and hence the inequality sign changes}

8/x^3 > -6

8 > - 6x³ {Multiplying both sides with x³}

6x³ > - 8 {Interchanging the sides}

x^3 > -8/6

⇒ x > - 1.1

So,  a = - 1.1

Answer:

  a = 3

Step-by-step explanation:

The function can be written as ...

  f(x) = 4/(x -3)^2

This has a vertical asymptote at x=3 and will be decreasing for all values of x to the right of that -- on the interval (3, ∞).

  a = 3

Answer: 7/12

Step-by-step explanation:

given data:

Box A

white ball = 1

red ball = 2

total ball = 3.

Box B

white ball = 1

red ball = 3

total ball = 4

Probability of picking a white ball as the final pick.

= 1/3 + 1/4

get the LCM = 12

= 4*1 + 1*3 /12

= 4 + 3 /12

= 7/12

Answer:

19

Step-by-step explanation:

3(x + 6) = 5(x - 4)

Distribute on both sides.

3x + 18 = 5x - 20

Subtract 3x from both sides. Add 20 to both sides.

38 = 2x

Divide both sides by 2.

Answer:

x= 105 also because it's a z angle

y= 180-105

=75

x=z which is 105, because they are alternative angles.

The given angle of 105 and angle z are consecutive interior angles and need to equal 180 degrees.

Z = 180-105 = 75 degrees

Angle z and angle c are vertical angles and are identical so angle x also equals 75 degrees

Angle y and 105 are supplementary angles and when added equal 180

Angle y is 180-105 = 75

X, y and z are all 75 degrees

Answer: x<-1/4

Step-by-step explanation:

Given

-3/x<12

Multiply x on both sides

-3/x · x<12 · x

-3<12x

Divide 12 on both sides

-3 / 12 < 12x / 12

Answer:

x = -12

Step-by-step explanation:

3x-24=5x

3x-5x=24 (move x's to same side by adding 24, and subtract 5x)

-2x = 24 (combine like variables, 3x-5x)

x = -12 (divide by -2)

Answer: The same number of tickets was sold on the fourth day and tenth day.

Step-by-step explanation:

Given: [tex]T(d)[/tex] is a function that relates the number of tickets sold for a movie to the number of days 'd' since the movie was released.

Also, the  average rate of change in T(d) for the interval d = 4 and d = 10 is 0.

Since the average rate determines the rate of change in the dependent variable (T(d)) with respect to the independent variable (d).

It means that there is no change from 4th day to 10th day in the number tickets sold.

Hence, the correct option is "The same number of tickets was sold on the fourth day and tenth day."

Answer:

A

Step-by-step explanation:

Using digit concepts, it is found that, in expanded form:

[tex]90.125 = 9 \times 10^1 + 0 \times 10^0 + 1 \times 10^{-1} + 2 \times 10^{-2} + 5 \times 10^{-3}[/tex]

--------------------

[tex]90 = 0 \times 10^{0} + 9 \times 10^{1} = 9 \times 10^{1} + 0 \times 10^{0}[/tex]

[tex].125 = 1 \times 10^{-1} + 2 \times 10^{-2} + 5 \times 10^{-3}[/tex]

Combining the integer and decimal parts, we get that the number in expanded form is:

[tex]90.125 = 9 \times 10^1 + 0 \times 10^0 + 1 \times 10^{-1} + 2 \times 10^{-2} + 5 \times 10^{-3}[/tex]

Answer:

0.1028938

Step-by-step explanation:

Given the following :

Average gold production in Northern Nevada =3.2 grams per short ton (2000 pounds)

Value of gold is measured in Troy ounces (ozt)

1 Troy ounces = 31.1 grams(g)

Number of Troy ounces of gold extracted from one short ton of Nevada ore ; let the number be t:

1 ozt = 31.1 g

t = 3.2 g

Cross multiply :

31.1 × t = 3.2 × 1

31.1t = 3.2

t = 3.2 / 31.1

t = 0.1028938 ozt

Hence, On average, 0.1028938 ozt of gold is extracted from one short ton of Nevada ore
