Solve for x.

x + 2.6 = 1.7

Answers

Answer:

x = -0.9

Step-by-step explanation:

We must isolate the x variable. We can do this by subtracting 2.6 from both sides.

x + 2.6 - 2.6 = 1.7 - 2.6

x + 0 = -0.9

x = -0.9

Hope this helps!!

x + 2.6 = 1.7
x = 1.7 - 2.6
x = -0.9

Answer: Enlargement x1.5

Step-by-step explanation:

from the image provided, the figure’s length and width have been increased (larger/smaller figure: width 12/8 = 1.5, length 9/6 = 1.5)

Total students= 27; girls:total students = 2:3. How many boys and girls are there?

Answers

Answer:

18 girls and 9 boys

Answer:

Step-by-step explanation:

2:3 ?:27

How does 3 get to 27? x9. 2 x 9? 18

2:3 18:27

Information: 18 girls and 27 students.

The others must be boys. 27 - 18 = 9

There are 9 boys and 18 girls. Ratio: 9 to 18 or 9:18 or 9/18 You can simplify to 1 boy for every 2 girls. Ratio: 1 to 2 or 1:2 or 1/2

A group of seventh graders and a group of teachers at a local middle school were asked how many siblings they each have. The dot plots below show the results. Students A dot plot titled Students. A number line going from 0 to 9 labeled number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9. Teachers A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9. When comparing the shape of the two sets of data, what conclusion can someone draw? The students tend to have fewer siblings than the teachers. The teachers tend to have fewer siblings than the students. Both the students and the teachers have a wide range of siblings. Both sets of data have the same shape. the answer is- a. The students tend to have fewer siblings than the teachers.

Answers

Answer:

A. The students tend to have fewer siblings than the teachers.

Step-by-step explanation:

First we need to draw the dot plots correctly. If you count both sides they have 20 each.

Now, clearly none have fewer nobody here yet has more or less but going on to the next step.

Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14. And so on.

On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.

So the answer is A. The students tend to have fewer siblings than the teachers.

Answer:

The sum is A

Find the median and mean of the data set below:
31
,
38
,
35
,
36
,
3
31,38,35,36,3

Answers

To find the median, we need to first arrange the data set in order from least to greatest:

3, 31, 35, 36, 38

The median is the middle value in the data set. Since there are five values in the data set, the middle value is the third value, which is 35. Therefore, the median of the data set is 35.

To find the mean, we need to add up all the values in the data set and divide by the total number of values:

(3 + 31 + 35 + 36 + 38) / 5 = 28.6

Therefore, the mean of the data set is 28.6.

you find the mean by adding every value together and dividing by the number of values. 143 / 5 = 28.6
the median is always the middle number so the median is 35. hope this helps you to remember in the future

The dot plot shows the number of movies 15 people watched in a month: Dot plot labeled Number of Movies Seen shows 2 dots over 0, 2 dots over 7, 3 dot over 8, 3 dots over 9, and 5 dots over 10. Is the median or the mean a better center for this data and why? (1 point) Mean; because the data is normally distributed and has an outlier Mean; because the data clusters on the right and is not symmetric Median; because the data is normally distributed and has an outlier Median; because the data clusters on the right and is not symmetric

Answers

Answer:Median; because the data is not symmetric and there are outliers.

Step-by-step explanation:We know that a median is a central tendency of a data and it best represents the given data set.

From the given information we see that the data is skewed to the right since most of the data points takes the higher value and the data is not symmetric as it is skewed.

Hence, last option is the correct answer.

Can you help me(explain at simplest if you can)

Answers

Answer:

Length: 6

Width: 5

Step-by-step explanation:

Givens:

Let L=length and w=width

Area= 30 = Lw

Perimeter = 22 = L + L + w + w= 2L + 2w

L= w+1

Plug in the values into the equation for the perimeter

22= 2L+ 2w

22= 2(w+1)+ 2w

22=2w+2+2w

22=4w+2

20=4w

5=w

Plug w into the equation for L

L=w+1

L=6

We don't have to use the formula for area in this question.

Honestly I think the easiest way to thing of this problem is by looking at a multiplication table. This method won’t work for more complex problems, but for this one I think it will be the easiest method to understand. If you want a more in detail explanation just reply to this and Ill explain how to solve it using equations.
Basically, for any method you need to know the equation for Area and for Perimeter (I will be using • to represent multiplication):
Area(A) = L•W
Perimeter(P) = L + L + W + W
You can also think of perimeter as
P = 2L + 2W
Since we know that the length of the rectangle needs to be 1 unit longer than the width, you basically need to find 2 numbers with a difference of 1 that multiply together to get 30 and that can be multiplied by 2 and added together to get 22. If you look at a multiplication chart you will see that 6 and 5 are 1 unit apart and multiply to get 30. Also, 6•2=12 and 5•2=10. If you add 12 + 10 you get 22. Therefore, your solution would be:

L = 6
W = 5

Like I said I’m happy to assist you further if you want to know how to solve it using more complex equations, which will be necessary on more advanced problems. Just let me know if you want me to! Hope this helped good luck!

so basically you can just tell me where the boxes go and bam you get 20 points

Answer: Using the corrected exponents on the reposted question:. D is the choice.

Step-by-step explanation:

5.29÷9.32=0.567596 That would be equivalent to 5.676×10-¹, like 1/0 of 5.676.

Then to calculate 10 ^-9 divided by 10^-7, we subtract the -7 from -9. -9 -(-7) = -2

That leaves us with 10-² × 10-¹ so adding the exponents we have 10-³ to multiply by 5.676 for the scientific notation.
