Solve the equation. What is X?
6 ( x − 2 ) = −18
(It is NOT -5, 5, -6, 6 I kept on getting that as the answer)
Answers
\(6(x-2)=-18\)
Distribute:
\((6)(x)+(6)(-2)=-18\)
\(6x-12=-18\)
Add 12 to both sides:
\(6x-12+12=-18+12\)
\(6x=-6\)
Divide both sides by 6:
\(\dfrac{6x}{6} =\dfrac{-6}{6}\)
\(\fbox{x = -1}\)

a) In the first event, the eighth graders are running a baton relay race with three other classmates. The team’s top speed for each leg is 56.81 seconds, 59.22 seconds, 57.39 seconds, and 60.11 seconds. Use the information to predict the team’s best time for the race.
If the team’s best time for the race is less than 4 minutes, then the eighth graders earn 40 points. If not, the seventh graders earn 40 points. Which grade should be awarded 40 points?
Answers
Answer:
233.53 s
Step-by-step explanation:
The sum of best times for the legs is ...
56.81 +59.22 +57.39 +60.11 = 233.53 . . . seconds
Without additional information about the effects of training or the normal variation in times, this is the best prediction we can make.

(2x-10)(x+3)+(x3+1)(x-4) what does it equal to
Answers
Answer:
Step-by-step explanation:
Use FOIL method.
(2x - 10)(x + 3) = 2x*x + 2x*3 + (-10)*x + (-10)*3
= 2x² + 6x - 10x - 30 {Combine like terms}
= 2x² - 4x - 30
(x³ + 1)(x - 4) = x³*x + x³ *(-4) + 1*x + 1*(-4)
= x⁴ - 4x³ + x - 4
(2x - 10)(x +3) +(x³ +1)(x - 4) = 2x² - 4x - 30 + x⁴ - 4x³ + x - 4
Combine like term
= x⁴ - 4x³ + 2x² - 4x + x -30 - 4
= x⁴ - 4x³ + 2x² - 3x - 34
Answer:
Use the FOIL method.
(2x - 10)(x + 3) = 2x*x + 2x*3 + (-10)*x + (-10)*3
= 2x² + 6x - 10x - 30 {Combine like terms}
= 2x² - 4x - 30
(x³ + 1)(x - 4) = x³*x + x³ *(-4) + 1*x + 1*(-4)
= x⁴ - 4x³ + x - 4
(2x - 10)(x +3) +(x³ +1)(x - 4) = 2x² - 4x - 30 + x⁴ - 4x³ + x - 4
Combine like term
= x⁴ - 4x³ + 2x² - 4x + x -30 - 4
= x⁴ - 4x³ + 2x² - 3x - 34

Do you see any areas in your data or points that could be considered clusters or outliers? Explain your answer in complete sentences.
Trolls will be reported
Answers
Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.
So basically the units are counting up by 5.
The x axis is age in years and y axis is the number of US states named in 60 seconds.
Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.
(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

1. Is the average change in population the same now as it was 50 years ago? Explain your answer.
2. Reflect on the interpretation of your data.
3. What should you consider when comparing population growth (or decline) over different intervals of time? Hint: What factors influence population growth or decline? Explain fully and provide examples where needed.
Answers
1. The average change in population is not the same now as it was 50 years ago. The population growth rate can vary greatly from year to year and decade to decade, and is influenced by a variety of factors such as birth and death rates, immigration, and emigration. Therefore, it is important to analyze the specific data for each time period to determine the average change in population.
2. When interpreting data on population growth or decline, it is important to consider the factors that influence population change and to analyze the data in the context of the specific time period being studied. It is also important to consider the accuracy and reliability of the data source, as well as any potential biases or limitations in the data.
3. When comparing population growth or decline over different intervals of time, it is important to consider a range of factors that can influence population change, such as birth and death rates, migration patterns, economic and environmental conditions, and government policies. For example, population growth rates in a country may be influenced by changes in healthcare access or advancements in technology that reduce infant mortality rates or increase life expectancy. In addition, migration patterns can greatly impact population growth rates, as some regions may experience large influxes of immigrants or emigrants at different periods in time. When comparing population data over different intervals of time, it is important to take into account these and other factors that may contribute to population growth or decline.

The Spurs charge an entrance fee of $15.50 and $2 per drink. The Rampage charge an entrance fee of $8 and $3.50 per drink. How many drinks, d, must be purchased in order for the total cost at the Spurs game and Rampage game are the same? A 2 drinks B 3 drinks C 4 drinks D 5 drinks
Answers
Answer:
D
Step-by-step explanation:
For every drink bought at the game, the difference in the cost changes by 1.50. The difference between the entrance fees is 7.50 so just divide 7.50 by 1.50 to get 5.

The answer choice which corrects solves the given equation; 9 (x + y) = 3y + h is; Choice D; x = ( 1/9 ) (h - 6y).
What is the solution of the equation for x?It follows from the task content that the equation given in the task content is to be solved for variable, x.
Since the given equation is;
9 (x + y) = 3y + h
The equation can be solved as follows;
9x + 9y = 3y + h
Subtract 9y from both sides of the equation;
9x = 3y - 9y + h
9x = h - 6y
Divide both sides of the equation by 9;
x = (h - 6y) / 9
x = ( 1/9 ) (h - 6y)
Therefore, the answer choice which solves the equation for x correctly is; Choice D; x = ( 1/9 ) (h - 6y).
