Answer:
You must divide by 3.
Step-by-step explanation:
3x / 3 = x
9 / 3 = 3
Hence x = 3
Answer:
divide by 3 on both sides of the equation
Step-by-step explanation:
3x = 9
The variable x is being multiplied by 3. You want x alone, so you must use the opposite operation of multiplication to undo the multiplication by 3. The opposite of multiplication is is division. Since x is being multiplied by 3, you must divide by 3. The rule of equations is that you must do the same operation to both sides of the equation, so you must divide both sides of the equation by 3.

What does it mean to translate an x and y coordinate into a composition?
Answer: When a point or figure on a coordinate plane is moved by sliding it to the right or left or up or down, the movement is called a translation. The figure is translated from one position to another. Example 1: A point is located at (3, 7) on the coordinate plane. In geometry, a translation is the shifting of a figure from one place to another without rotating, reflecting, or changing its size. This is done by moving the vertices of the figure to the prescribed number of spaces on a coordinate plane and then drawing the new figure. There are four main types of transformations: translation, rotation, reflection, and dilation. These transformations fall into two categories: rigid transformations that do not change the shape or size of the preimage and non-rigid transformations that change the size but not the shape of the preimage.

Solve:
3(x - 2) = 12
Answer:
x=6
Step-by-step explanation:
3(x-2)=12
divide both sides by 3
x-2=4
add 2 to both sides
x-2+2=4+2
combine like terms
x=6
Answer:
x = 6
Step-by-step explanation:
So the equation looks like this:
3(x - 2) = 12
So the first thing we are going to do in this equation is multiply 3 by x and -2 in order to get rid of the parenthesis:
3(x - 2) = 12
(3 * x) + (3 * (-2)) = 12
3x - 6 = 12
Now we are going to add 6 to -6 and what you to one side of the equation you do to the other:
3x - 6 = 12
+ 6 + 6
3x = 18
Now in order to segregate the variable x from 3 we are going to have to divide 3x by 3 and what you do to one side of the equation you do to the other:
3x/3 = 18/3
x = 6
Now in order to check our work we are going to replace the variable x with six in the equation:
3(x - 2) = 12 = 3((6) - 2) = 12
(3 * 6) + (-2 * 3) = 12
18 - 6 = 12
12 = 12
Tada, hope this helps you!!
Suppose IQ scores were obtained for 20 randomly selected sets of twins. The 20 pairs of measurements yield x overbarequals103.26, y overbarequals102.05, requals0.897, P-valueequals0.000, and ModifyingAbove y with caret equals negative 13.47 plus 1.12 x, where x represents the IQ score of the twin born first. Find the best predicted value of ModifyingAbove y with caret given that the twin born first has an IQ of 105? Use a significance level of 0.05.
Answer
The value is [tex]P = 131.07[/tex]
Step -by -step -explanation :
From the question we are old that
The sample size is n = 20
The sample mean for the first person of each twin is [tex]\= x = 100.45[/tex]
The sample mean for the second person of each twin is [tex]\= y = 103[/tex]
The correlation between both data is r = 0.908
The p-value is p-value = 0.000
The equation [tex]\^ y = 13.47 + 1.12 x[/tex]
Here we are told that x represents the first person to be given birth to among each twin
The value of x considered is x = 105
Generally given that p-value = 0.000
Then the Predicted value of [tex]\^ y[/tex] is mathematically represented as
[tex]P = 13.47 + 1.12 (105)[/tex]
=> [tex]P = 131.07[/tex]

Step-by-step explanation:
You might keep your money in a bank, but have you heard of a time
bank? This online service allows users to trade
services with one
another without exchanging money. For example, a hairdresser gives
someone a haircut for one hour of credit in the time bank. The
hairdresser could then use that credit to have a plumber come work for
her for an hour. Time banks are useful for people who can't arrange
direct trades. The plumber might not want a haircut, but he can work
for the hairdresser and earn credit to use with someone else.
How does the detail "The plumber might not want a haircut, but he can work
for the hairdresser and earn credit to use with someone else" best support
the central idea that time banks are a convenient way to get things done?
Explanation:
Of course, the plumber might not want a haircut, but he might have a wife, a fiancee, or a sister who may need the services of a hairdresser so working for the hairdresser would earn him credit that can be used by any of these people. So in a sense, he is getting things done for others.
Therefore, the time-bank service solves a problem by allowing people to receive services without exchanging money.

The sum of 9/26 and -4/13 is ____
Answer:
1/26
Step-by-step explanation:
-4/13 is equivalent to -8/26. Since 9/26 and -8/26 have the same denominator, you can add together the numerator to get the numerator of the final answer. 9-8 is 1, so your answer is 1/26.

Which relation is a function? Group of answer choices (2, 7), (6, 5), (4, 4), (3, 3), (2, 1) (9, −3), (9, 3), (4, −2), (4, 2), (0, 0) (1, 0), (3, 0), (1, 1), (3, 1) (1, 3) (1, 1), (2, 2), (3, 3), (4, 4), (5, 8)
Given:
The relations in the options.
To find:
The relation which is a function.
Solution:
Consider the options are :
(a) {(2, 7), (6, 5), (4, 4), (3, 3), (2, 1)}
(b) {(9, −3), (9, 3), (4, −2), (4, 2), (0, 0)}
(c) {(1, 0), (3, 0), (1, 1), (3, 1) (1, 3)}
(d) {(1, 1), (2, 2), (3, 3), (4, 4), (5, 8)}
A relation is a function if there exist a unique y-value for each x-value.
In option (a), y=7 and y=1 at x=2. So, it is not a function.
In option (b), y=-3 and y=3 at x=9. So, it is not a function.
In option (c), y=0 and y=1 at x=3. So, it is not a function.
In option (d), there are unique y-value for each x-value. So, it is a function.
Therefore, the correct option is (d).

Answer:
11.2 or just 11
Step-by-step explanation:
Okay, so, I apologize if this is an idiot answer, but if you take your 168 hikers and divide them by each room which can hold 15 hikers, you'll get 11.2. NOW MAYBE THE .2 OF THE HIKERS CAN SLEEP ON THE FLOOR I DON'T KNOW SORRY IF THIS IS A TERRIBLE ANSWER.

Step-by-step explanation:
two of the triangles' corresponding angles are the same even if the side lebgths are not, making these two similar
By AA similarity triangle ABC and triangle LMN are similar. Therefore, option A is the correct answer.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
In the given triangle ABC, ∠A=50° and ∠B=75°.
In the given triangle LMN, ∠L=50° and ∠M=75°
From the given triangles,
∠A=∠L=50°
∠B=∠M=75°
By AA similarity triangle ABC and triangle LMN are similar.
Therefore, option A is the correct answer.

Answer:
x = 8
Step-by-step explanation:
Interior angles of a triangle always add up to 180 degrees.
50 + 76 + ? = 180
? = 180 - 126
? = 54
A straight line also is always 180 degrees.
54 + 15x + 6 = 180
15x = 180 - 60
15x = 120
x = 8

Suppose Metro by T-Mobile wants to offer a simple extended warranty plan. If your phone is damaged, they will repair it for up to $50. If you lose or destroy your phone, they will give you a $200 voucher towards a new phone. The company believes that 5% of customers will need the replacement voucher and 10% will request a repair. What is the standard deviation?
Answer:
45
Step-by-step explanation:
Given that :
Voucher awarded (x) :
Repair = $50
Lose or destroy = $200
P(x):
Replacement voucher = 5%
Repair voucher = 10%
X ______ 50 ______ 200
P(x) ____ 0.1 _______ 0.05
Expected variance Var(X) :
ΣX²p(x) - E(x) ;
E(x) = Σx*p(x) = (50*0.1) + (200*0.05) = 15
ΣX²p(x) = Σ[(50^2 * 0. 1) + (200^2 * 0.05)] = 250 + 2000 = 2250
Var(X) = 2250 - 15^2 = 2025
Standard deviation = √Var(x)
Standard deviation = √2025
Standard deviation = $45
