What is 3 (2x + 4) = 12?

Answers

Answer 1
2x+4=4
2x=0
The answer is
X=0
Answer 2

Answer:

Hi!!

The answer is = 0

Step-by-step explanation:

1. Distribute

3(2+4)=12

6+12=12

2. Subtract 12 from both sides of the equation

6 + 12= 12

6 + 12 − 12 = 12 − 12

3.Simplify

part A. 6 + 12 − 12 = 12 − 12

6x = 12 - 12

part B. 6x = 12 - 12

6x = 0

Hope this helps!! =)

The line plots below show the numbers of hours for the 12 students in each class.
The distance between the means of Class A and Class B is 4 hours.
Find the mean absolute deviation (MAD) for each class.

Answers

Answer:

for class A

mean ={3+4+8(5)+6+7)/12}=5hours

mean absolute deviation (MAD) for A

=[|5-3|+|5-4|+8|5-5|+|5-6|+|5-7|]/12=6/12=1/2

for class B

mean =4 hours given

mean absolute deviation (MAD) for B

=[|4-7|+|4-8|+8|4-9|+|4-10|+|4-11|]/12=60/12=5

Answer:

See below

Step-by-step explanation:

class-1:

we are given some data 3,4,5,5,5,5,5,5,5,5,6,7

we want to figure out the MAD (Mean absolute deviation) of the given database

remember that,

[tex] \rm\displaystyle \: MAD = \frac{1}{n} \sum_{i = 1} ^{n} |x_{i} - m(x)| [/tex]

where m(X) represents the mean of the given database and [tex]|x_{i}-m(X)|[/tex] tells us to subtract every data with the got mean and n represents the number of data

let figure out m(X)

[tex] \rm\displaystyle \: m(x) = \frac{3 + 4 + 5(8) + 6 + 7 }{12} [/tex]

simplify multiplication:

[tex] \rm\displaystyle \: m(x) = \frac{3 + 4 + 40 + 6 + 7 }{12} [/tex]

simplify addition:

[tex] \rm\displaystyle \: m(x) = \frac{60}{12} [/tex]

simplify substraction:

[tex] \rm\displaystyle \: m(x) = 5[/tex]

let's figure out [tex]\sum[/tex] and [tex]|x_i-m(X)|[/tex]

[tex] \displaystyle\begin{array} {|c |c| } \hline |x_{i} - m(x) | & \displaystyle\sum_{i = 1} ^{n} |x_{i} - m(x) | \\ \hline |3 - 5 | & 2 \\ \hline | 4 - 5 | &1 \\ \hline |5(8) - 5(8)| &0 \\ \hline |6 - 5|&1 \\ \hline |7 - 5| &2 \\ \hline \\ \text{total} & 5 \\ \hline\end{array}[/tex]

last part let's figure out MAD

[tex] \displaystyle \: MAD = \frac{5}{12} [/tex]

simplify division:

[tex] \displaystyle \: MAD = 0.42[/tex]

Class-2:

likewise class-2

given database 7,8,9,9,9,9,9,9,9,9,10,11

figure out m(X)

[tex] \rm\displaystyle \: m(x )= \frac{7 + 8 + 9(8) + 10 + 11}{12} [/tex]

simplify multiplication:

[tex] \rm\displaystyle \: m(x )= \frac{7 + 8 + 72 + 10 + 11}{12} [/tex]

simplify addition:

[tex] \rm\displaystyle \: m(x )= \frac{108}{12} [/tex]

simplify division:

[tex] \rm\displaystyle \: m(x )= 9[/tex]

likewise

figure out [tex]\sum[/tex] and [tex]|x_i-m(X)|[/tex]

[tex] \displaystyle\begin{array} {|c |c| } \hline |x_{i} - m(x) | & \displaystyle\sum_{i = 1} ^{n} |x_{i} - m(x) | \\ \hline |7 - 9 | & 2 \\ \hline | 8- 9 | &1 \\ \hline |9(8) - 9(8)| &0 \\ \hline |10 - 9|&1 \\ \hline |11- 9| &2 \\ \hline \\ \text{total} & 5 \\ \hline\end{array}[/tex]

figure out MAD

[tex] \displaystyle \: MAD = \frac{5}{12} [/tex]

simplify division:

[tex] \displaystyle \: MAD = 0.42[/tex]

HELP PLEASE

Answers

Answer:

$362.64

Step-by-step explanation:

Assuming that "S" represents the money in U.S. dollars, we are given the starting amount as 270 pounds.

We first need to convert the pounds into euros, since £1 = €1.11

So all we have to do is £270 × €1.11 = €299.70

Then, we need to convert euros into dollars, since €1 = $1.21

So all we have to do here is €299.70 × $1.21 = $362.637

Which rounds to $362.64

The triangle is an isosceles right triangle, and the true statements about the triangle are

The triangle must be an isosceles triangle. The triangle must be a right triangle. The triangle must contain an angle measuring 45°

How to determine the true statements?

The given parameters are:

Angle = 90 degrees

Two side lengths = 5 cm

Given that one of the angles is 90 degrees, then it means that the triangle is a right triangle.

Also since two sides are equal, then the triangle is an isosceles triangle, and the other angles are 45 degrees each

Hence, the true statements about the triangle are (a), (c) and (e)

Answers

Answer:

m∠SBE = 26°,  [tex]m\hat O B[/tex] = 126°

Step-by-step explanation:

The arc of a circle is a portion of the circumference of the circle. For a circle, the degree measure of an arc is equal to the measure of the central angle that intercepts the arc.

Central angle is an angle whose vertex is on the center of the circle and endpoints on the circumference of the circle. If the endpoints of the central angle are are also the endpoints for the angle's intercepted arc, then both angles are congruent.

Also, the angle at the center is twice the angle at the circumference.

Angle at center = [tex]m\hat S E[/tex] = 52° (central angle is congruent with angle that intercept the arc)

2 * m∠SBE = central angle (angle at the center is twice the angle at the circumference)

2 * m∠SBE = 52

m∠SBE = 26°

2 * m∠BEO = central angle (angle at the center is twice the angle at the circumference)

2 * 63 = central angle

central angle = 126°

Angle at center = [tex]m\hat O B[/tex] = 126° (central angle is congruent with angle that intercept the arc)

Find the area and perimeter of a rectangle that has a length of (x + 24) and (x + 16). Show all work for full credit.

Answers

Answer:

Perimeter of rectangle = 4x + 80

Area = x² + 40x + 384

Step-by-step explanation:

Perimeter of rectangle = 2*(length + width)

                                      = 2* (x + 24 + x + 16)

                                      = 2*( x +x + 24 + 16)    {Combine like terms}

                                      = 2* (2x + 40)

Use Distributive property : a*(b +c) = a *b + a*c

                                     = 2*2x + 2*40

                                     = 4x + 80

Area of rectangle = length * width

                             = (x + 24) (x + 16) {use FOIL method}

                            = x*x + x*16 + 24*x + 24*16

                             = x² + 16x + 24x + 384  {Combine like terms}

                             = x² + 40x + 384

Step-by-step explanation:

Farah needs 4 and 4/5 pounds of tomatoes & and additional 5 and 3/5 pounds of tomatoes to make soup.

Find the 11th term in the geometric sequence: 4, 6, 9,....

Answers

Answer:

A11 = 230.66015625

Step-by-step explanation:

hi!

the first thing that you have to do when solving for the 11th term in a geometric sequence is to find the common ratio!

I did this by dividing 6/4 = 3/2 (I did multiply this by 6 to test if it was correct, and it was)

the next thing you can do is use this formula:

An = A1*r^(n-1)

An = the nth term of the sequence

A1 = the first term in the sequence

r = common ratio

n = the number of term that you are solving for

A11 = 4*(3/2)^(11-1)

A11 = 4*(3/2)^10

A11 = 230.66015625

Find the value of x. Round your answer to the nearest tenth.

Answers

Answer:

+4√5

Step-by-step explanation:

Note that this is a right triangle.  Therefore, the lengths of the three sides are related through the Pythagorean Theorem:  a^2 + b^2 = c^2, where c is the length of the hypotenuse.  

Thus, x^2 + 19^2 = 21^2, or, after solving this for x^2,

x^2 = 441 - 361 = 80

x is therefore +√80, or +4√5.
