Step-by-step explanation:

its up side down

Answer:

✅question 1.) D) n + 3

1/2( 2n + 6 )
distribution property
1/2 x 2n = 1n = n

1/2 x 6 = 3

N + 3

✅question 2.) A) x + 9

3x - ( 2x + 4 ) + 5

Combine like terms

3x - 2x = 1x = x

4 + 5 = 9

X + 9

✅question 3.) D) y = 54.5x

327 - 163.5 = 163.5

6 - 3 = 3

163.5/3 = 54.5

Check

y= mx + b

327 = 54.5 x 6 + B

327 = 327 + B

327 - 327 = 0

B = 0

Y = 54.5x

✅question 4.) C) 2x - 6

2(3 - x) - 12 + 4x

Distribution property

6 - 2x - 12 + 4x

Combine like terms

4x - 2x = 2x

12 - 6 = 6

2x - 6

✅question 5.) C) -38
-5 = y-7/9

Convert -5 to a fraction

-5 x 9 = -45

-5 = -45/9

-45/9 = y - 7/9

Cancel out -7/9 by adding 7/9 and what you do to one side do to the other

-45/9 +7/9 = -38/9

-38/9 = y/9

Y= -38

Check

-5 = -38 - 7 / 9

-5 = -45/9

-45/9 = -5

-5 = -5

Step-by-step explanation:

To solutions for the questions on two quantities are;

1. Time (in hours) and the miles of road paint. The independent quantity is time (t), and the dependent quantity is miles of road painted (m). t for time and m for miles. The equation that relates these two quantities is: m = 9.5 + 0.25t

2. The rate at which the painting crew is painting the road, which is 0.25 mile per hour. This means that for every hour the crew works, they paint 0.25 mile of the road.

3. 10 miles

4. 10 more hours to complete half of the job.

5. quantities                            Time               Miles

                                                  -36                   0

1. The equation m = 9.5 + 0.25t represents a linear relationship between two variables, m and t.

The equation indicates that the crew has already painted 9.5 miles before they start painting at the rate of 0.25 mile per hour. As the crew continues to work (increasing t), the total miles painted (m) increases by 0.25 miles for every additional hour they work. The equation helps to determine the total miles painted by the crew after a certain amount of time.

If the crew works for another 2 hours, we can find the total miles they will complete using the equation:

m = 9.5 + 0.25(2)

m = 9.5 + 0.5

m = 10

The Department of Transportation in each state is responsible for the improvements and repairs of that state's roads. One important job is to repaint the road lines that have worn away or faded. A painting crew is painting a 24-mile stretch of road. They have already completed a total of 9.5 miles of the road. The crew has been painting at a rate of 0.25 mile per hour and continues to paint at the same rate.

1 Identify the two quantities that are changing in this situation, identify the independent and dependent quantities, and define the variables for these quantities. Then write an equation that relates the two quantities.

2 What is the unit rate of change in this situation? Explain.

3 How many total miles of the road will the crew complete if it works for another 2 hours?

4 How many more hours does the crew need to work to complete half of the job?

Answer: 15

Step-by-step explanation:

1/3 times 45 is 15

We can predict that the die will land on a number greater than 4 approximately 15 times out of 45 rolls.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Since we are interested in the number of times the die lands on a number greater than 4, we can add the probabilities of rolling a 5 or a 6.

Therefore, the probability of rolling a number greater than 4 on one roll is:

P(5 or 6)

= P(5) + P(6)

= 1/6 + 1/6

= 1/3

To predict how many times the die will land on a number greater than 4 out of 45 rolls, we can multiply the probability of rolling a number greater than 4 on one roll by the number of rolls:

= 45 x (1/3)

= 15

Therefore, we can predict that the die will land on a number greater than 4 approximately 15 times out of 45 rolls.

Answer: 18+7, 20+7, or 25+7

Step-by-step explanation:

18+7=25

20+7=27

25+7=32

which are all greater than 24

y would be anything over 17

Answer:

y can be equal to:

1. 18

2. 19

3. 20

Step-by-step explanation:

To be able to find what y could be, not just 3 numbers, you can solve it like a regular equation.  

First subtract 7 from both sides:

17 < y

So, any values above 17 (17+) could be what y is.

Let's go with 18, 19, and 20 for this example.

24 < 18 + 7

24 < 19 + 7

24 < 20 + 7

When the right side of all 3 inequalities are solved, you get 25, 26, and 27, which are all greater than 24, making these inequalities true.

The total profit that Tom earned last week from the sale of furniture was $968

The average profit on the pieces that Tom built and sold last weekend was $242.

To find the profit earned on each piece of furniture, we need to subtract the expenses from the selling price. The profit can be calculated using the formula:

Profit = Selling Price - Expenses

Using the given data, we can calculate the profit for each piece of furniture:

Dresser: $640 - $176 = $464

Rocking Chair: $165 - $42 = $123

Shelf: $40 - $15 = $25

Table: $475 - $119 = $356

To find the total profit earned, we add up the profit for each piece:

Total Profit = $464 + $123 + $25 + $356 = $968

To find the average profit, we add up the profits for each piece of furniture and divide by the total number of pieces:

Average Profit = (464 + 123 + 25 + 356) / 4 = $242

The transformation that is happening to the car is dilation.

Dilation is a transformation in which the size of an object changes. It occurs when all the points of an object are scaled in one direction or another from a center point.

In this case, the car has been dilated, which means that it has been scaled up or enlarged in size. The original length of the car, which was 4 units, has been increased to a new length of 6 units. This means that all the points of the car, such as its corners, wheels, and body, have been moved away from the center point of dilation in a consistent manner to create a larger version of the original car.

Step-by-step explanation:

the first persons mistake:

-6/-3 isn't -2 it's 2 so they divided wrong

the second persons mistake:

they added 7 instead of taking it away which is why they got 8 instead of -6

how to work it out:

-3w+7=1

first take away 7 from both sides

-3w=-6

then divide each side by -3 to get w by itself

w=2

Answer:

w=2

Step-by-step explanation:

The mistake on the first problem is that -6 / -3 does not equal negative 2, it equals positive 2.

The mistake on the second problem is that 1 - 7 does not equal 8, it equals -6
