Answer: can it be a fraction?

Step-by-step explanation:

Answer: y = 4/3 + 1/4x

Step-by-step explanation: 6y - 1.5x = 8

Add 1.5x to get y alone, 6y = 8 + 1.5x

Divide everything by 6, y = 8/6 + 1.5x/6

Simplify, y = 4/3 + 1/4x

Answers:

x=4 and y=27

x=8 and y=-1

x=1 and y=216

Step-by-step explanation:

You have to plug all of the choices given into the equation until it equals to 7

∛12 + 3 = 2.9 +3 = 5.29

∛27 + 4= 3 + 4 = 7

∛16 + 3 = 2.5 +3 = 5.5

∛-1 + 8 = -1 + 8= 7

∛216 + 1 = 6 + 1= 7

∛30 - 3 = 3.11 - 3 = 0.11

∛3 + 4 = 1.44 + 4= 5.44

Answer: 600

Step-by-step explanation:

Answer:

-60

Step-by-step explanation:

Increase in population is given by positive sign

Change in population in 5 years = -300

Decrease in population is represented by negative sign

Change in population in 1 year = -300\5

                                                = -60

Town's population faces a decrease of 60 residents each year.

Answer:

It will take Rosa 5 and a half (5.5) weeks to have the same amount of money in both accounts.

Step-by-step explanation:

For this problem, we will have to set two expressions equal to each other. The first expression will represent Rosa's saving account, which already has $117 in it. Every week ([tex]x[/tex]), she adds $21 to her savings account:

[tex]21x+117[/tex]

The second expression will represent Rosa's checking account. Rosa's checking account already has $95 in it. Every week ([tex]x[/tex]), she adds $25 to her checking account:

[tex]25x+95[/tex]

Now that we have our two expressions, set them equal to each other. This is our equation that will be used to find the number of weeks ([tex]x[/tex]) it takes until Rosha has the same amount of money in both accounts:

[tex]21x+117=25x+95[/tex]

Subtract [tex]21x[/tex] from both sides of the equation:

[tex]117=4x+95[/tex]

Subtract [tex]95[/tex] from both sides of the equation:

[tex]22=4x[/tex]

Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]4[/tex]:

[tex]5.5=x[/tex]

[tex]x=5.5[/tex]

So it will take five and a half weeks for her accounts to have the same amount of money.

_

Check your work by substituting [tex]5.5[/tex] into the initial equation:

[tex]21(5.5)+117=25(5.5)+95[/tex]

[tex]115.5+117=137.5+95[/tex]

[tex]232.5=232.5[/tex]

Since the accounts have the same amount, the answer is correct!

Answer: 6 boxes. average 45 each.

Step-by-step explanation:

The mean of a dataset if the average of the dataset.

The new mean mass of the remaining boxes is 44 kg

From the question, we have:

[tex]\mathbf{\bar x = 45}[/tex] --- mean of 6 boxes

The mean of a dataset is:

[tex]\mathbf{\bar x = \frac{\sum x}{n}}[/tex]

So, we have:

[tex]\mathbf{45 = \frac{\sum x}{6}}[/tex]

Multiply by 6

[tex]\mathbf{45 \times 6= \sum x}[/tex]

[tex]\mathbf{\sum x = 270}[/tex]

One of the boxes is 50 kg.

So, the mass of the remaining boxes is:

[tex]\mathbf{Mass = 270 - 50}[/tex]

[tex]\mathbf{Mass = 220}[/tex]

The mean of the remaining boxes is:

[tex]\mathbf{\bar x = \frac{\sum x}{n}}[/tex]

[tex]\mathbf{\bar x = \frac{220}{5}}[/tex]

[tex]\mathbf{\bar x = 44}[/tex]

Hence, the new mean mass of the remaining boxes is 44 kg

Step-by-step explanation:

4 - 5k = -21

Transpose and subtract 4 from both sides:

4 - 4 - 5k = -21 -4

-5k = -25

Divide both sides by -5

-5k/-5 = -25/-5
