Is -2/3(12b - 6 + 9b - 18) equivalent to 2b(b + 8)? Show your work.
Answer:
No, they are not equivalent
Step-by-step explanation:
[tex]\frac{-2}{3}(12b - 6 + 9b - 18) = \frac{-2}{3}(12b + 9b - 6 - 18)\\\\=\frac{-2}{3}(21b - 24)\\\\ = \frac{-2}{3}*21b -24*\frac{-2}{3}\\\\= -2*7b + 8*2\\\\= 2( -7b + 8)[/tex]
Answer:
This is NOT equivalent to 2b(b + 8).
Step-by-step explanation:
Start with -2/3(12b - 6 + 9b - 18). Simplify this. First, combine the like terms inside the set of parentheses:
(-2/3)(21b - 24)
Simplify this by applying the distributation property of multiplication:
-14b + 16
Finally, factor out 2: 2(-7b + 8)
This is NOT equivalent to 2b(b + 8).

Answer: 1176 cm2
Step-by-step explanation:
- The position of an object moving in a straight line
is given by s = 2t^2 - 3t, where s is in meters and t
is the time in seconds the object has been in
motion. How long (to the nearest tenth) will it
take the object to move 11 meters?
PLEASE HELP AND SHOW WORK ILL GIVE 20 PTS
Answer:
s(t) = 2t^2-3t
19 = 2t^2-3t
2t^2-3t-19=0
t = [3 +- sqrt(9-4*2*-19)]/4
t = [3 +- sqrt(161)]/4
t = [3 +- 12.6886]/4
Positive answer:
t = [3+12.6886]/4
t = 3.9221 seconds

Yupin is making fruit punch. The recipe calls for 2 ½ of guava juice. The guava juice container has 4 ¼ cups of juice in it. How many cups of guava will be left in the container after Yupin makes the punch?
Answer:
1 [tex]\frac{3}{4}[/tex] cups
Step-by-step explanation:
Convert the numbers to decimals, then subtract the amount needed from the amount in the juice container:
4.25 - 2.5
= 1.75
This is equivalent to the fraction 1[tex]\frac{3}{4}[/tex]
So, after Yupin makes the punch, there will be 1[tex]\frac{3}{4}[/tex] cups of guava juice left in the container
Trish is ordering t-shirts from a website that charges a certain amount per t-shirt plus a flat rate for shipping. The cost for a given number of t-shirts is shown in the table.
20a. Write an equation to represent the situation. (Write your answer with no spaces, all lowercase letters, and write the slope as a decimal)
20b. What does the slope mean in the context of the situation?
20c. What does the y-intercept mean in the context of the situation?
Answer:
20a. y = 8.75x - 5.99
20b. slop is the cost of each shirt.
20c. I am not to sure on this one so I am going to guess that it means payment to enter the shop.

Three shipping companies want to compare the mean numbers of deliveries their drivers complete in a day.
The first two shipping companies provided their data from a sample of drivers in a table.
Company C showed its data in a dot plot.
Answer the questions to compare the mean number of deliveries for the three companies.
1. How many drivers did company C use in its sample?
2. What is the MAD for company C's data? Show your work.
3. Which company had the greatest mean number of deliveries?
4. Compare the means for companies A and B. By how many times the MAD do their means differ? Show your work.
Answer:
1. the company C used 10 drivers2. 6 + 7 + 8 + 9 + 10 + 10 + 10 + 12 + 14 + 14 = 100/10. The Mean = 10 (6- 10) + (7- 10) + (8- 10) + (9- 10) + (10- 10) + (10- 10) + (10- 10) + (12- 10) + (14- 10)4 + 3 + 2 + 1 + 0 + 0 + 0 + 2 + 4 = 16/10 = 1 6/103. The groups that had the most deliveries where group A and B4. So if there are 6 deliveries of group A and 14 deliveries from group B i think the MAD would be 4
Step-by-step explanation:
The mean absolute deviation of company C's data is 2.
What is a dot plot?A dot plot, also known as a strip plot or dot chart, is a simple form of data visualization that consists of data points plotted as dots on a graph with an x- and y-axis. These types of charts are used to graphically depict certain data trends or groupings.
The mean absolute deviation (MAD) is the mean distance between each data value and the mean of the data set.
Number of drivers used by company C in its sample = 10
Mean absolute deviation for company C's data = 2
Company B has the greatest mean number of deliveries.
The mean deliveries of company B is 4 times MAD of company A.
We are given the sum of each point from the mean. It is 20.
Mean absolute deviation of company C = 20/10 = 2.
Mean A = 6
Mean B = 14
Mean B - Mean A = 8 = 4×2 = 4 times MAD (since MAD =2 for both companies).
Therefore, the mean absolute deviation of company C's data is 2.

At Mike's Moving Supplies, cardboard boxes are sold in packs of 5. Depending on the size, the
most a pack of boxes can cost is $20.
Let x represent how much each box costs. Which inequality describes the problem?
5x < 20
5x > 20
Solve the inequality. Then, complete the sentence to describe the solution.
Each box costs at most $4
Submit
The inequality describes the problem is 5x < 20.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
The pack of boxes can cost is $20.
Let x represent how much each box costs.
So, the inequality describes the problem
5x < 20
If we solve the above inequality
x< 4
So, the price of each box can cost less than 4.
