To make the expression 4x-2 + (2x + 4) equivalent to 2(6x + 7), what must be the value in the box?
[tex]4x - 2 + (2x + 4) = 2(6x + 7) \\ [/tex]
[tex]4x - 2 + 2x + 4 = 12x + 14[/tex]
Simplification
[tex]6x + 2 = 12x + 14[/tex]
Subtract sides 2
[tex]6x + 2 - 2 = 12x + 14 - 2[/tex]
Simplification
[tex]6x = 12x + 12[/tex]
Subtract sides -12x
[tex]6x - 12x = 12x - 12x + 12[/tex]
Simplification
[tex] - 6x = 12[/tex]
Divided sides by -6
[tex] \frac{ - 6}{ - 6}x = \frac{12}{ - 6} \\ [/tex]
[tex]x = - 2[/tex]
It is must be in the box buddy.
And we're done...♥️♥️♥️♥️♥️
Help me please I don’t get it I put false and my teacher said it’s wrong
ur teacher is wrong im in algebra 2 an this is correct
20. The temperature of a city during a week was 1° C, -6°C, 14°C, -9°C,
-15°C, 8°C and -7°C. What was the average daily temperature of the town
for the week?
The average temperature would be -2°Celsius
You just add up all the numbers, and the average of the numbers is the sum of all the numbers divided by the amount of numbers.
1+-6+14+-9+-15+8+-7=-14
-14/7=-2
what information do you need to know to write an equation relating two quantities that have a proportional relationship
Answer:Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.
Step-by-step explanation:
What is the sum of zeros in this equation (m-10)(8m-1)=0? Enter your ancwer as a fraction. PLSSS I RLLYYY NEEDD HELPP
Answer:
m= 1/8, 10
Step-by-step explanation:
(8m − 1)(m − 10) = 0
↓
8m−1=0 → (8m/8)=(1/8) → m=(1/8)
m−10=0 → m=10
m=1/8
m=10

Describe and correct the errors in solving the absolute value inequality
х
5x + 4/> 13
x+4 -13 and x + 4 <13
x>-17 and
X<9
-17
22
There is an arithmetic error in both rewritten inequalities. The correct solution is -9<< < 17
The inequality symbols should be reversed. The correct solution is 9 > I > -17
The two inequalities should be written as one inequality -13 < 3+4 < 13. The correct solution is -17 <3 <9.
The compound inequalities should be joined by "or;" and both inequality symbols should be reversed. The correct solution is
< 17 ore 9.
Answer:
Step-by-step explanation:
Given the inequality [tex]|x+4|>13[/tex], to solve, we will solve the negative and positive value of the modulus for x as shown:
If the modulus is positive:
[tex]x+4>13\\[/tex]
subtract 4 from both sides
[tex]x+4-4>13-4\\x>9[/tex]
If the modulus is negative
[tex]-(x+4)>13\\-x-4>13\\[/tex]
Add 4 to both sides
[tex]-x-4+4>13+4\\-x>17[/tex]
Multiply both sides by -1
[tex]-(-x)<-17\\x<-17\\-17>x[/tex]
Combine both inequalities. If:
[tex]x>9\\[/tex]
Combining with [tex]-17>x[/tex] will give:
[tex]-17>x>9[/tex]

Answer:
80 degrees
Step-by-step explanation:
both intersections are the same, so we can count them as one. We notice that one line is a straight line compared to other so we can subtract 100 from 180 and get 80
Answer:
80
Step-by-step explanation:
Vertical angles equal 360 in total and the angles across from each other equal the same. 100 x 2 = 200
360-200 = 160
160/2 = 80

Safety regulations require that the time between airplane takeoffs (on the same runway) will be at least 4 minutes. When taking off, the run time of an airplane on the runway is 24 seconds. Planes are on average waiting 5 minutes and 54 seconds for take-off. On average there are 12 planes taking off per hour. How many planes are either on the runway or waiting to take off?
Answer:
1 plane either on the runway or waiting to take off
Step-by-step explanation:
We are given;
Frequency of take off = 12 planes per hour = 12/60 = 0.2 planes per minute
Waiting time on runway = 5 minutes 54 seconds = 5.9 minutes
Run time on runway = 24 seconds = 24/60 minutes = 0.4 minutes
To solve this question, we will use Little's law which is given by the formula;
System inventory = rate of flow × throughput time
Now, rate of flow is the same as Frequency of take off.
Thus, rate of flow = 0.2 planes per minute
Throughput time = Waiting time on runway + Run time on runway
Thus;
Throughput time = 5.9 minutes + 0.4 minutes
Throughput time = 6.3 minutes
Thus;
System inventory = 0.2 × 6.3 = 1.26 planes
Thus is approximately 1 plane.

State whether the data described below are discrete or? continuous, and explain why. The volumes left parenthesis in cubic feet right parenthesis of different rooms Choose the correct answer below. A. The data are discrete because the data can take on any value in an interval. B. The data are discrete because the data can only take on specific values. C. The data are continuous because the data can take on any value in an interval. D. The data are continuous because the data can only take on specific values.
Answer:
The correct answer is:
The data are continuous because the data can take on any value in an interval. (C)
Step-by-step explanation:
Discrete data are data that can take on certain limited values. There is a limit to what values can be assigned to such data. For example, the number of children in a school will just be whole numbers, either 20 or 50 or 55 or 108, etc, you cannot have 100.5 children. This makes it limited to the values it can take on, hence it is discrete
Continuous data, on the other hand, are data that can take on any value within a scale. The possibility of assigning a value is unlimited. for example height. The height can be 3m, 3.8m, 4.57m, etc, there's no limit to the possibility that a height can take. Other examples are; temperature, weight, acceleration, volume etc. In this example the volume of a room in cubic feet can be 30ft³, 50.6ft³, etc. The possibilities are endless, hence it is a continuous data.

If 3x + 7 = 10, what is -2x - 8?
Answer:
-10
Step-by-step explanation:
first you need to solve the first equation
3x + 7 = 10
subtract 7 from both sides
3x + 7 - 7 = 10 - 7
3x = 3
divide both sides by 3
3x/3 = 3/3
x = 1
now substitute x in the second equation.
-2x - 8
-2(1) - 8
-2 - 8
-10
Answer:
- 10
Step-by-step explanation:
Given
3x + 7 = 10 ( subtract 7 from both sides )
3x = 3 ( divide both sides by 3 )
x = 1
Thus
- 2x - 8 = - 2(1) - 8 = - 2 - 8 = - 10

4. A recipe for orange water says, "Mix 3 teaspoons yellow water with 1 teaspoon red water." For this recipe, we might say: "The ratio of teaspoons of yellow water to teaspoons of red water is 3 : 1." Write a ratio for 2 batches of this recipe. Write a ratio for 4 batches of this recipe.
Answer:
2 batches of orange water = 6 tablespoon of yellow water and 2 tablespoon of red water
4 batches of orange water = 12 tablespoon of yellow water and 4 tablespoon of red water
Step-by-step explanation:
1 batch
Yellow water = 3 teaspoons
Red water = 1 teaspoons
Yellow water : Red water = 3 : 1
2 batches of orange water
Multiply the ratios by 2
Yellow water : Red water
= (3 : 1) * 2
= 6 : 2
2 batches of orange water = 6 tablespoon of yellow water and 2 tablespoon of red water
4 batches of orange water
Multiply the ratios by 4
Yellow water : Red water
= (3 : 1) * 4
= 12 : 4
4 batches of orange water = 12 tablespoon of yellow water and 4 tablespoon of red water
Answer:
2 batches of orange water = 6 tablespoon of yellow water and 2 tablespoon of red water
4 batches of orange water = 12 tablespoon of yellow water and 4 tablespoon of red water
Step-by-step explanation:
1 batch
Yellow water = 3 teaspoons
Red water = 1 teaspoons
Yellow water : Red water = 3 : 1
2 batches of orange water
Multiply the ratios by 2
Yellow water : Red water
= (3 : 1) * 2
= 6 : 2
2 batches of orange water = 6 tablespoon of yellow water and 2 tablespoon of red water
4 batches of orange water
Multiply the ratios by 4
Yellow water : Red water
= (3 : 1) * 4
= 12 : 4
4 batches of orange water = 12 tablespoon of yellow water and 4 tablespoon of red water
