Answer:

[tex]\frac{-13}{5}[/tex] or -2.6

Step-by-step explanation:

To do this you would first have the equation [tex]5(x+4)=12[/tex] and then you could multiply the x+5 by 5 which is 5x+25 so then your equation would be [tex]5x+25=12[/tex] then you would subtract 25 from both sides to cancel out the 25 so then your equation would look like this [tex]5x=-13[/tex] then you would divide from both sides to just get x so you would get  [tex]x=\frac{-13}{5}[/tex] so you could leave it as is or you could turn it into a decimal which is -2.6

Answer:

Step-by-step explanation:

a) The probability that a california adult is an internet user, given that he or she is a college graduate can be represented with the following

P(internet user|college graduate) = P(internet user ∩ college graduate) P(college graduate) = 0.19/26= 0.7307

= 0.73

b) The probability that a randomly chosen internet user is a college graduate?

P(college graduate|internet user) = P(internet user ∩ college graduate) P(internet user) = 0.19/0.31= 0.6129

= 0.61

Answer: DJ receive 12 requests for hip-hop songs on Friday night.

Step-by-step explanation:

As per given , we have

[tex]\text{(Number of request country songs ) = }2+\dfrac{4}{3}\times (\text{Number of request for hip-hop songs})[/tex]

Let X represents the number of request for hip-hop songs which equation represents the situation .

If  they're 18 request for country songs, then

[tex]18=2+\dfrac{4}{3}X\\\\\Rightarrow\ 18-2 =\dfrac{4}{3}X\\\\\Rightarrow\ 16 =\dfrac{4}{3}X\\\\\Rightarrow\ X=\dfrac{3}{4}\times16= 3\times4=12\\\\\Rightarrow\ X=12[/tex]

Hence, DJ receive 12 requests for hip-hop songs on Friday night.

Answer:

El número de hombres = 8 hombres

El número de mujeres = 7 mujeres

El número de niños = 5 niños

Step-by-step explanation:

El número total de personas en la excursión = 20

La suma de los hombres y las mujeres = 3 veces el número de hijos

El número de mujeres = 1 menos el número de hombres

Sea el número de hijos = A

Sea el número de mujeres = B

Sea el número de hombres = C

Tenemos;

B + C = 3 × A .................... (1)

B = C - 1 .......................... (2)

A + B + C = 20 .............. (3)

Sustituyendo el valor de A + B en la ecuación (1) en la ecuación (3), tenemos;

A + B + C = 20

A + 3 × A = 20

4 × A = 20

A = 5

Sumando la ecuación (1) a la ecuación (2), obtenemos

B + C + B = 3 × A + C - 1

2 · B + C - C + 1 = 3 · A

2 · B + 1 = 3 · A = 3 × 5 = 15

2 · B + 1 = 15

B = (15 - 1) / 2 = 7

B = 7

De la ecuación (2),

B = C - 1

7 = C - 1

C = 7 + 1 = 8

El número de niños = 5

El número de mujeres = 7

El número de hombres = 8.

Expanding brackets.

[tex]\sf (9x - 7xy)(9x-7xy)[/tex]

Applying the FOIL method.

[tex]\sf 9x(9x-7xy)-7xy(9x-7xy)[/tex]

[tex]\sf 81x^2 -63x^2 y -63x^2 y+49x^2 y^2[/tex]

Combining like terms.

Answer:

S = 60

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out equation

S + 3(2 + x) = -36

Step 2: Define variables

x = 6

Step 3: Plug in variables

S + 3(2 + 6) = -36

Step 4: Parenthesis

S + 3(8) = -36

Step 5: Multiply

S + 24 = -36

Step 6: Subtract 24 on both sides

S = 60

Answer:

x > 0 and y > 0

Step-by-step explanation:

If the point (x,y) is in Quadrant I, then that means both x and y must be positive.  For this to be true, x must be greater than 0 and y must be greater than 0.

Answer:

[tex]y=-4x+16[/tex].

Step-by-step explanation:

From the given graph it is clear that the y-intercept is 16.

The line passes through (-2,24) and (2,8). So, slope of line is

[tex]Slope=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]Slope=\dfrac{8-24}{2-(-2)}[/tex]

[tex]Slope=\dfrac{-16}{4}[/tex]

[tex]Slope=-4[/tex]

Slope intercept form of a line is

[tex]y=mx+b[/tex]

where, m is slope and b is y-intercept.

Substitute m=-4 and b=16 in the above equation.

[tex]y=(-4)x+(16)[/tex]

[tex]y=-4x+16[/tex]

Therefore, the required equation is [tex]y=-4x+16[/tex].

Answer:

About 2 cups.

Step-by-step explanation:

Use 3 and 4's LCM (Least Common Multiple).

3 and 4's LCM is 12.

Rewrite the fractions.

2/3 rewrites into 8/12.

1 1/4 rewrites into 1 3/12.

Add the fractions.

You should get 1 11/12.

Unfortunately there are no "cups" that go up to twelths. Here you will have to round.

1 11/12 is close to 2 cups.

Each color occupies 1/6 of the school wall

The fraction of each color that occupies the wall will be 1/6.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

A school painted 1/2 of a school wall has its exercise center with 3 tones each variety takes a similar measure of room on the wall.

The fraction of the color that occupies the wall will be given as,

⇒ (1/2) x (1/3)

⇒ 1/6

The small part of each variety that possesses the wall will be 1/6.

Answer: [tex]f(x)= x+40000[/tex]

Step-by-step explanation:

We write a function f(x) which gives the values of the function that are dependent on the independent variable "x".

Given: The number of miles on the odometer can be represented by the equation y = x + 40, 000, where y is the number of miles on the odometer, and x is the number of miles you have driven it.

Here y is dependent on x, so we replace y by f(x), then we get

[tex]f(x)= x+40000[/tex]   which is the required answer.

Answer:

r = 2

Step-by-step explanation:

nth term of a geometric sequence = [tex] ar^{n - 1} [/tex].

Where,

a = first term, r = common ratio,

We are given that, the 11th term is 32 times larger than the 6th term of the geometric sequence. Thus:

the 6th term can be expressed as [tex] ar^{n - 1} = ar^{6 - 1} [/tex]

[tex] a_6 = ar^{5} [/tex]

The 11th term is expressed as [tex] a_11 = ar^{10} [/tex]

Since the 11th term is 32 times larger than the 6th term, therefore, the following equation can be derived to find the common ratio, r, of the sequence:

[tex] a_11 = 32*a_6 [/tex]

[tex] a_11 = ar^{10} [/tex]

[tex] a_6 = ar^{5} [/tex], therefore:

[tex] ar^{10} = 32*ar^{5} [/tex]

Divide both sides by ar⁵

[tex] \frac{ar^{10}}{ar^5} = \frac{32*ar^{5}}{ar^5} [/tex]

[tex] r^5 = 32 [/tex]

[tex] r^5 = 2^5 [/tex]

[tex] r = 2 [/tex]

Common ratio = 2

Answer: Priscilla can make 8 bracelets in 48 minutes.

Step-by-step explanation:

So the givens are that:

2 bracelets in 12 minutes, how many in 48 minutes

So find the ratio of bracelets to minutes:

2/12 simplified is 1/6

So Priscilla can make 1 bracelet per 6 minutes. We just need to find how many in 48 minutes.

1/6 * 8 = 8/48

So Priscilla can make 8 bracelets in 48 minutes.

Hence your answer.

Answer:

Set; subset.

Step-by-step explanation:

A group of objects or numbers is called a set while a part of a set is called a subset. The objects or numbers that make up a set are generally referred to as elements or members and are written inside a pair of curly braces {}.

A set can be made up of elements such as numbers, alphabets, people, cars etc.

For instance, Set A = {2, 4, 6, 8, 10, 12} represents all the even number between 1 - 12.

On the other hand, a subset is a part of a larger set.

For instance, comedy movies, horror movies, romance movies, action movies are a subset of movies.

Answer:

96

Step-by-step explanation:

f(x) = 3 – 5x

f(-8) + f(-10) = 96

f(-8) + f(-10) =  96

f(-8) = 3 - 5×(-8)

= 3 + 40

= 43

f(-10) = 3 - 5×(-10)

= 3 + 50

= 53

f(-8) + f(-10) = 43 + 53 = 96

Answer:

L(t) = 170 - 10t

Step-by-step explanation:

Alexa borrowed some money from her friend in order to help buy a new video game system. Alexa agreed to pay back her friend $10 per week and originally borrowed $170. Write an equation for L, in terms of t, representing the amount Alexa owes her friend after t weeks.

Let

Initial amount Alexa borrowed= L(o)

Amount Alexa pays per week= k

Number of weeks= t

Amount Alexa owes her friend after t weeks= L(t)

The amount that Alexa owes after t weeks is given by the equation:

L(t) = L(o) - kt

Where,

L(o) = $170

k= $10

Substituting the values into the equation, we have,

L(t) = L(o) - kt

L(t) = 170 - 10t

Therefore,

The amount Alexa owes her friend after t weeks is given by

L(t) = 170 - 10t

Answer:

7 t-shirts

Step-by-step explanation:

Because you know the cost of shipping ($6) is constant no matter the quantity you order (fixed cost), you can subtract it from the total cost of the order to find the total variable cost. Next you divide the left over cost by the cost per t-shirt to get the quantity ordered.

$111 - 6 = $105

$105 / $15 per shirt = 7 t-shirts
