Simplify the following expression: (7x - 9y) + (2x - 7) - (-x + 5)

Answer:

I think option G is the correct answer

I think it will help you.

Answer:

G

Step-by-step explanation:

30/(x+3)

it doesn't matter the order of the numbers for addition so the numbers in the parenthesis don't really matter which order they are in.

F

Each of these answer choices represents a different property of equality; however, only answer choice F uses the properties of equality (PoEs) correctly.

Answer Choice F

The first answer choice shows the distributive property. This property states that multiplying a number by a factor in parentheses is the same as multiplying the number outside the parentheses by each of the terms within the parentheses.

Answer Choice G

This answer choice attempts to show the associative property. The associative property states that when doing addition, the placement of the parentheses does not matter. However, this answer uses addition and multiplication, so the associative property does not apply.

Answer Choice H

This answer choice tries to show the commutative property. The commutative property states that addition and multiplication can be done in andy order. However, this only applies to addition and multiplication. So, it cannot be used for division.

Answer Choice J

This answer choice tries to use the associative property similar to the second answer. However, as I stated earlier, this property only works for addition. So, the use of multiplication in the expression makes it so they are not equal.

Answer:

F is your answer

Step-by-step explanation:

Answer Choice F

The first answer choice shows the distributive property. This property states that multiplying a number by a factor in parentheses is the same as multiplying the number outside the parentheses by each of the terms within the parentheses.

Answer:

Step-by-step explanation:

Step 1:  Solve inside the parenthesis

[tex](6 + 4) * 3 - 4 / 2[/tex]

[tex](10) * 3 - 4 / 2[/tex]

Step 2:  Multiply the left side

[tex]10 * 3 - 4 / 2[/tex]

[tex]30 - 4 / 2[/tex]

Step 3:  Divide the right side

[tex]30 - 4 / 2[/tex]

[tex]30 - 2[/tex]

Step 4:  Subtract from each other

[tex]30 - 2[/tex]

[tex]28[/tex]

Answer: [tex]28[/tex]

Answer: Answer:

There is moderate level of overlap between the two data sets.  

Step-by-step explanation:

Overlap of data sets.

Overlap measures the degree of duplication that exists within data sets.

It is an indicator of the degree to which data are identical.

We are given two data sets in the question.

We have to find the amount of overlap in data set 1 and in data set 2.

There are 8 data points in data set 1 as shown in the image.

There are 8 data points in the data set 2 as shown in the image.

Out of the 8 data points for both data set 1 and data set 2, 5 data points overlap each other on 6, 7, 8 and 9.

Thus, we could say there is moderate level of overlap between the two data sets.

Answer:

The profit is $0.75 per muffin.

Step-by-step explanation:

If P = .75m, then if m is 0, then P is zero (if the baker sells no muffins, they make no money)

If m = 1 (sold 1 muffin)

then P = .75, they made 75cents.

"for each muffin sold" means for 1 muffin.

Answer: They are both the same height of 1 1/2.

Step-by-step explanation:

1/2 x 3 = 1/2 x 3/1 = 3/2 = 1 1/2

3/4 x 2 = 3/4 x 2/1 = 6/4 = 1 2/4 = 1 1/2

Answer:

OPTION B

B. [tex]\frac{47}{120} ; \frac{1}{6}[/tex]

Step-by-step explanation:

A number cube is rolled 120 times; The number 4 comes up 47 times.

First, we have to determine the experimental probability of rolling a 4.

The formula to evaluate probability of an event is given; Probability = [tex]favorable outcomes/totaloutcomes[/tex]

Probability of rolling a 4; the total number of times when 4 appears/the total number of times number cube rolled= [tex]\frac{47}{120}[/tex]

We have to find the theoretical probability of rolling a 4.

Total number of outcomes number cube; 1,2,3,4,5,6

Probability of rolling a 4; [tex]\frac{1}{4}[/tex]

OPTION B IS CORRECT

I will only be writing the reasons for each and you can respond if you need clarification for anything:

3. def rectangle

4. SAS (side angle side congruence theorem)

5. CPCTC (congruent parts of congruent triangles are congruent)

Answer:

0.56

Step-by-step explanation:

0.56 Because you would have yo subtract 0.77 and 0.21

Answer:

Mean- 24.5

Median- 24

Range- 29

Mode- 24

Step-by-step explanation:

So you put the minimum, lower quartile then the Median on the box.

After that put upper quartile then the maximum.

So it should go 10,16,24,34.5,39

Answer:

10, 16, 24, 34.5, 39

Answer:

7.2 | 6.2 | 2.2 | -2.8 | -3.8 | -8.8

0.2

Step-by-step explanation:

Step 1) Find the mean

How to find it?

Add all the numbers listed above and divide by the number of numbers in the set (6)

This mean you should get 67/6=11.2

Step 2) Find the distance from the mean.

How do I do this?

Since you are trying to find the difference you will use the equation 11.2-(number)

Example) 11.2-4=7.2

This will give you the answers for the second half of the table.

Step 3) Find the mean of those distances to find the mean absolute deviation

How do I do this?

Add all the numbers on the second half of the table and then divide by 6. This will give you your mean absolute deviation.

I hope this helps! :D

Answer:

N=1

Step-by-step explanation:

If N = 1 then  4(1)= 4 whitch is less than 11

But if you plug in any other number

4(4) = 16

4(9) = 36

4(11) = 44

you can see that all of these are greater than 11, but we need something that is less than which would be N=1

Answer:

D

Step-by-step explanation:

In this problem, the length is 40 feet and the width is  25 feet.

25 is close to half of 40 so one side has to be abnout half the size as the other side.

The rectangle that fits this is rectangle D

Answer:

D

Option 2: 5/4

Step-by-step explanation:

7/1 = 28/4

28/4 × x = 8 3/4

28/4 × x = 35/4

x = 35/4 ÷ 28/4

= 35/4 × 4/28

= 140/112

= 5/4

Answer:

Its 5/4, the second one

Answer:

Option C, 488 square centimeters

Step-by-step explanation:

Step 1:  Determine the area of the rectangle

[tex]A = l * w[/tex]

[tex]A = 22\ cm * 17\ cm[/tex]

[tex]A = 374\ cm^2[/tex]

Step 2:  Determine the area of the triangle

[tex]A=\frac{h*b}{2}[/tex]

[tex]A=\frac{19\ cm * (22\ cm-10\ cm)}{2}[/tex]

[tex]A=\frac{19\ cm * (12\ cm)}{2}[/tex]

[tex]A=\frac{228\ cm^2}{2}[/tex]

[tex]A=114\ cm^2[/tex]

Step 3:  Determine the total area

[tex]A_{total} = 374\ cm^2 + 114\ cm^2[/tex]

[tex]A_{total} =488\ cm^2[/tex]

Answer:  Option C, 488 square centimeters

Answer:

we need to see more. You did not show what the data was so we can figure out the answer.

Answer:

Question 1: 34.56 mm

Question 2: 12.57 in

Question 3: 15.70 yd

Step-by-step explanation:

Answer:

10. 91.08mm

11. 33.12in

12. 41.4yd

Step-by-step explanation:

To find the answer to each, we first need to calculate the circumference:

(use 3.14 for π)

(2 * Diameter) * π = Circumference

Then half the circumference (because it is a semicircle) and add it to the diameter once again to accommodate for the middle line.

(Circumference / 2) + Diameter

Do this for each semi-circle as shown here:

10. (2 * 22) * 3.14 = 138.16

(138.16 / 2) + 22 = 91.08

11. (radius is given so double the middle)

(2 * (2 * 4)) * 3.14 = 50.24

(50.24 / 2) + 16 = 33.12

12. (2 * 10) * 3.14 = 62.8

(62.8 / 2) + 10 = 41.4

Answer:

-120-x

Step-by-step explanation:

Given:

[tex]\displaystyle \large{|120+x| \quad (x < -120)}[/tex]

This is the same as previous one. Recall modulus property:

[tex]\displaystyle \large{|a+x| = \begin{cases} a+x \quad (x \geq -a) \\ -a-x \quad (x < -a) \end{cases}}[/tex]

Keep in mind that |x+a| and |a+x| are equal via addition property.

Since the question gives interval of x < -120:

Therefore, the expression is -120-x
