Answer:

10

Step-by-step explanation:

153 - 143 = 10 (I'm not sure if this helped)

Answer:

n + 153 = 143

Step-by-step explanation:

In this sentence, we can use the keywords used to find the operations used in  its equation form. The first part has the words "added to." This tells us we need to add. So, on one side of the equation, we have n plus 153. This is the same as, or equal to, 143.

n plus 153 is equal to 143.

n + 153 = 143

The answer is n + 153 = 143.

Good luck ^^

Answer:

a = 9

Step-by-step explanation:

First we need to add  (x^2+3x)  to (3x^2+ax),

(x^2+3x)+(3x^2+ax)

Expand

= x^2+3x+3x^2+ax

Collect the like terms

= x^2+3x^2+3x+ax

= 4x^2 + 3x + ax

= 4x^2+(3+a)x

Equate the solution to 4x^2+12x

4x^2+(3+a)x = 4x^2+12x

Comparing the like terms on both sides

(3+a)x =12x

3 + a = 12

a = 12 - 3

a = 9

Hence the value of a is 9

x(17-x)

8(17-8)

8(9)

=72

Answer:

QUESTION:

If x = 8, what is the value of x(17 - x)?

ANSWER:

x( 17 - x) = ?

8( 17 - 8) = ?

8 X 17 = 136

8 X (-8) = -64

Step-by-step explanation:

Answer:

32

Step-by-step explanation:

the median in a data set is the middle number. first, you are going to want to order the numbers in numerical order.

this is what it would look like.

16, 21, 28, 30, 34, 45, 58, 60

(basically how it is in the problem lol)

since there's an even number of numbers in the set, you have to take the mean of the two middle numbers. in this case, the two middle numbers are 30  and 34.

you take the mean of numbers by adding them, and then dividing them based on the number of numbers. (sorry if that doesn't make sense, just look down ehe)

(30+34)/2

we divide by two because there are two numbers.

(30+34)/2

(64)/2

if this didn't make sense - sorry - but you can watch this video: https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-data-statistics/mean-and-median/v/mean-median-and-mode

The answer is "[tex]153.86 \ in^2[/tex]"

Step-by-step explanation:

The circular light which fits around rather than is sufficiently large for fire a camera is indeed a ring light. The ring light provides light with very little darkness, as the bright light is very close to a lens's vertical system. It's also usually called glamour or brightness of beauty.

Let's Each light surface area has [tex]38.465\ in^2[/tex].

Answer:

Price of each senior citizen ticket  is $12 and one child ticket is $3

Step-by-step explanation:

The price of one senior citizen ticket is $ 4.50.

Let x = price of one senior citizen ticket and y = price of one child ticket.

Now, since On the first day, the school sold 14 senior citizen tickets and 1 child ticket for a total of $66.50. WE have that

14x + y = 66.50  (1)

Also, on the second day, the school sold 2 senior citizen tickets and 2 child tickets for a total of $16.00. We have that

2x + 2y = 16.00  (2)

From (1), y = 66.50 - 14x

Substituting y into (2), we have

2x + 2y = 16.00  

2x + 2(66.50 - 14x) = 16.00  

2x + 2(66.50 - 14x) = 16.00  

2x + 133 - 28x = 16

2x - 28x = 16 - 133

-26x = -117

x = -117/-26

x = 4.5

So, the price of one senior citizen ticket is $ 4.50.

Answer:

-23

Step-by-step explanation:

We are given the functions;

h(x) = 5x - 3 and j(x) = -2x

Now, we want to find h[j(2)]

j(2) = -2(2)

j(2) = -4

Thus;

h(-4) = 5(-4) - 3

h(-4) = -20 - 3

h(-4) = - 23

Answer:

$4500

Step-by-step explanation:

Find how much she earned by dividing 234 by 0.052

234/0.052

= 4500

So, she earned $4500

Answer: see below

Step-by-step explanation:

Divide 234 by 5.2 to get one percent of her earnings, $45.

Multiply 45 by 100 to get 100% of her earnings, $4,500

If it asking for the gross earnings, leave it at $4,500

If it is asking for net earnings, subtract 234 from 4500 to get $4,266

The quotient is 2x² - 5x + 5, while the remainder is 0

Step-by-step explanation:

Given polynomial function;

4x³-12x²+15x-5 and a factor of 2x - 1

The quotient and remainder of the polynomial is calculated using the long division method;

                                         2x² - 5x + 5

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

                       2x - 1   √ 4x³-12x²+15x-5

                                    - (4x³ -  2x²)

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

                                               -10x² + 15x - 5

                                            - ( -10x² + 5x)

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

                                                          10x - 5

                                                      -  (10x - 5)

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

                                                                0

Therefore, the quotient is 2x² - 5x + 5, while the remainder is 0.

The system's solution is (xy, y) = and the k-value is 0. (4, -3).

Something that someone values are referred to as values. The things that only a person or a company considers "important" are, in other words, their values. Examples include valor, integrity, freedom, and inventiveness.

Value includes both the material and emotional cost of that possession. Only the item's monetary price may be considered its worth. An object's value often remains constant, although it might change based on the person and how much the thing means to them personally.

If [tex]x = 4[/tex], then we can substitute [tex]4[/tex] for [tex]x[/tex] in the second equation to get:

[tex]4 + y = 1[/tex]

Subtracting [tex]4[/tex] from both sides, we get:

[tex]y = -3[/tex]

Now we substitute [tex]x = 4[/tex] and [tex]y = -3[/tex]  into the first equation to solve for [tex]k[/tex]:

[tex]6x + 8y = k[/tex]

[tex]6(4) + 8(-3) = k[/tex]

[tex]24 - 24 = k[/tex]

[tex]k = 0[/tex]

Therefore, the value of [tex]k[/tex] is [tex]0[/tex], and the solution to the system is [tex](x, y) = (4, -3)[/tex]
