Help me find the values of x
1. 2x+1=9
2. 4x+3=19
3. 3x-2=7
____________________________________________________
If there's addition, use subtraction to find the value.If there's subtraction, use addition to find the value.x(y) means to multiply x with y____________________________________________________
1. In the first problem, we need to subtract 1 from 9 since there is an addition:
9 – 1 = 8
Next, divide 8 by 2, and we get:
8 ÷ 2 = 4
This means that x = 4
Finally, check the answer by:
2(4) + 1 = 9
2. In the second problem, we need to subtract 3 from 19 since there is an addition:
19 – 3 = 16
Next, divide 16 by 4, and we get:
16 ÷ 4 = 4
This means that x = 4
Finally, check the answer by:
4(4) + 3 = 19
3. In the third problem, we need to add 2 with 7 since there is subtraction:
2 + 7 = 9
Next, divide 9 by 3, and we get:
9 ÷ 3 = 3
This means that x = 3
Finally, check the answer by:
3(3) – 2 = 7
Hope this helps :)

Key: 2 | 1 | 0 means 12 for Bay Side and 10 for Seaside
Part A: Calculate the measures of center. Show all work. (2 points)
Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
PLEASE HELP ASAP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Part A: To calculate the measures of center, we can find the median and the mean for each school.
For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.
To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.
For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.
To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):
18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.
Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.
The measures of center for Seaside School are: median = 15, mean ≈ 15.9.
Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.
For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.
To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.
For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.
To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.
Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.
The measures of variability for Seaside School are: range = 15, IQR = 6.
Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.

four and five eighths, 462.5%, thirty seven eighths
four and six twenty fifths, 4.625%, thirty seven eighths
four and five eighths, 4.625%, forty five eighths
four and six twenty fifths, 462.5%, forty five eighths
Answer:
Step-by-step explanation:
4.625%- percents and decimals are the same
four and five eighths- five divided by eight is (.625) and 4+ (.625) is 4.625
thirty seven eighths- 37 divided by 8 is 4.625

What is the value of the expression m8−(34−n) in simplest form, when m = 6 and n = 18?
please hurry
Answer:
N is just simply 18
so 6*8-(34-18) and use pemdas to solve
34-18=16
6*8-16
48-16
32
so the value is 32
The value of the expression for m = 6 and n = 18 is 16,79,600.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is the expression as -
m⁸ - (34 - n)
The expression given is -
m⁸ - (34 - n)
Now, for m = 6 and n = 18, we can write -
6⁸ - 34 + 18
6⁸ - 16
(6 x 6) x (6 x 6) x (6 x 6) x (6 x 6) - (16)
36 x 36 x 36 x 36 - 16
16,79,616 - 16
16,79,600
Therefore, the value of the expression for m = 6 and n = 18 is 16,79,600.

A large container has a maximum capacity of 64 ounces. The container is filled with 8 ounces less than its maximum capacity. Answer parts a and b.
a. To what percent of its capacity is the large container filled?
The container is filled to 87.5% of the maximum capacity.
b. Some liquid will be poured from a full 16-ounce container until it is filled to the same percent of its capacity as the large container in part a. How many ounces of liquid must be poured from the full 16-ounce container? Explain.
Note: The answers go in the blanks
When the 16-ounce container is _____% filled, it will contain _____ ounce(s). So _____ ounce(s) will need to be poured from the full 16-ounce container.
Answer:
(a) 87.5%
(b) 90%, 14.4 oz, 1.6 oz
Step-by-step explanation:
You want the fraction full a 64 oz container is if it holds 8 oz less than its capacity. You also want to know the amount that must be transferred from a 16 oz container if both containers are to be the same fraction full.
a) FractionThe amount in the 64-ounce container is ...
64 oz - 8 oz = 56 oz
The fraction of its capacity this represents is ...
(56 oz)/(64 oz) = 7/8 = 87.5%
The container is filled to 87.5% of its capacity.
b) TransferIf x is removed from a 16-ounce container and added to the 64-ounce container, their respective fill fractions are ...
(16 -x)/16 and (56 +x)/64
We want these values to be equal, so ...
(16 -x)/16 = (56 +x)/64
4(16 -x) = 56 +x . . . . . . . . . multiply by 64
64 -4x = 56 +x . . . . . . . . . eliminate parentheses
8 = 5x . . . . . . . . . . . . . . . . add 4x-56
x = 8/5 = 1.6 . . . . . . . . . . . divide by 5
When 1.6 ounces are removed from the 16-ounce container, its fill fraction will be ...
(16 -1.6)/16 = 1 - 0.1 = 0.90 = 90%
The 16-ounce container will be 90% filled, and will contain 14.4 ounces.
So, 1.6 ounces will need to be poured from the full 16 ounce container.
__
Additional comment
After receiving 1.6 ounces, the larger container will have 57.6 ounces. Its fraction full will be 57.6/64 = 90%, as required.

Based on the information, we can infer that celebrity quotes include percentages to give their words more credibility.
What do celebrity quotes mean?To identify the meaning of famous quotes we must read them carefully and identify the key words to know the deep meaning of these sentences. According to the above, the meaning would be:
The first means that geniuses work harder than people think because their genius is generally related to their creativity. However, he points out that it is 99% work.
The second means that to be successful you have to fail many times. In this case, it refers to the fact that success is made up of 99% of failed attempts and the 100th attempt is the one that is successful.
The third refers to the fact that if we do not try to carry out a challenging activity, we are losing 100% of the possibilities of achieving it. On the contrary, if we try at least we will learn to do it.
