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

6у - 1.5х = 8
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

the mean mass of 6 boxes is 45kg. one of the boxes with a mass of 50kg is removed. calculate the new mean mass of the remaining boxes
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

Rosa has $117 in her savings account and $95 in her checking account. Each week she will put $21 into her savings account and $25 into her checking account. Complete the equation that can be used to find the number of weeks, x, until Rosa has the same amount of money in both accounts.
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:
5.5 weeksStep-by-step explanation:
GivenInitial balance
Savings account = $117Checking account = $95Added amount per week
Savings account = $21Checking account = $25If number of weeks is x, then required equation is
117 + 21x = 95 + 25xSolving for x
25x - 21x = 117 - 954x = 22x = 22/4x = 5.5The answer is 5.5 weeks

What is the slope of the line that passes through the points (-3, -3)(−3,−3) and (-18, -23) ?(−18,−23)? Write your answer in the simplest form.
Answer:
Let's see what to do buddy...
Step-by-step explanation:
_________________________________
Step (1)
To find the slope of linear functions using two points, we have the following equation :
[tex]slope = \frac{y(b) - y(a)}{ x(b) - x(a) } \\ [/tex]
Where a and b are two point of the function.
_________________________________
Step (2)
Well now I want to choose a name for the given points :
a = ( -3 , -3 ) ••••••••• b = ( -18 , -23 )
_________________________________
Step (3)
It's time to put the the coordinates in the above equation :
[tex]slope = \frac{ - 23 - ( - 3)}{ - 18 - ( - 3)} \\ [/tex]
[tex]slope = \frac{ - 23 + 3}{ - 18 + 3 } \\ [/tex]
[tex]slope = \frac{ - 20}{ - 15} \\ [/tex]
Negatives simplified :
[tex]slope = \frac{20}{15} \\ [/tex]
The face and denominator are reduced to five :
[tex]slope = \frac{4}{3} \\ [/tex]
_________________________________
And we're done.
Thanks for watching buddy good luck.
