Answer:
n + 6 = 7n
Step-by-step explanation:
"The sum of a number and six" would mean the number plus 6: n+6 and "is seven times the number" indicates that it would be equal to the product of 7 for n: 7n. According to this, the answer is that the translation of the sentence into an equation is: n+6=7n.
n − 6 = 7n is not right because the statement says the sum of a number and six.
7(n + 6) = n is not right because the statement indicates that seven multiplies n on the right side as it says seven times the number.
n = 7n + 6 is not right because the statement says the sum of a number and six which would be on the left side and that this would be equal to seven for n.

Point B is 1/3 of the way from A to C. What are the coordinates of C?
A = (-4 , -7)
B = (12 , 5)
Answer: C=(44,29).
Step-by-step explanation:
The given points are A = (-4 , -7) and B = (12 , 5).
It is given that Point B is 1/3 of the way from A to C.
AB:AC=1:3
AB:BC=AB:(AC-AB)=1:(3-1)=1:2
It means point B divides the line segment AC in 1:2.
Let coordinates of C are (a,b).
Section formula: If a point divides a line segment in m:n, then
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
Using section formula, we get
[tex]B=\left(\dfrac{1(a)+2(-4)}{1+2},\dfrac{1(b)+2(-7)}{1+2}\right)[/tex]
[tex](12,5)=\left(\dfrac{a-8}{3},\dfrac{b-14}{3}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{a-8}{3}=12[/tex]
[tex]a-8=36[/tex]
[tex]a=36+8[/tex]
[tex]a=44[/tex]
[tex]\dfrac{b-14}{3}=5[/tex]
[tex]b-14=15[/tex]
[tex]b=15+14[/tex]
[tex]b=29[/tex]
Therefore, the coordinates of C are (44,29).

· To provide some context, for an employee who earns $4,000 in each bi-weekly pay period in September through December, approximately $2,200 of Social Security taxes would be deferred. This same amount, of course, will need to be repaid beginning in 2021 and the employee’s paycheck would be reduced accordingly.
OCEAN Humpback whales are known to weigh as much as 8 x 104 pounds. The tiny krill they eat weigh only 2.1875 x 103 pounds. How many time greater than krill are humpback whales?
Answer:
The humpback whales are 37 times bigger than the krills they eat
Step-by-step explanation:
In this question, we are interested in knowing how much bigger are humpback whales compared to krill.
what is simply happening here is to divide the weight of the humpback whales by the weight of the krills.
From the question, weight of humpback whales = 8 * 10^4 while the weight of the krills are 2.1875 * 10^3
So the number of times the humpback whales are bigger is;
(8 * 10^4)/(2.1875 * 10^3) = 36.57 which are approximately 37 times bigger
Which is the name of a rat with endpoint A?
Answer:
AB
Step-by-step explanation:

Ken puts 4 fluid ounces of bubble mix into each bowl. How many bowls can he fill with 1 pint of bubble mix?
Answer:
4 bowls
Step-by-step explanation:
Conversion rate :
1 liquid pint = 16 fluid ounces
From the question, we are told that :
4 fluid ounces of bubble mix = 1 bowl
16 fluid ounces of bubble mix(1 liquid pint) = y bowl
Cross Multiply
4 fluid ounces × y bowl = 16 fluid ounces × 1bowl
y bowl = 16 fluid ounces × 1bowl/4 fluid ounces
= 4 bowls
Therefore, he can fill 4 bowls with 1 pint of bubble mix

The data in the table above was compiled by a new pet information website from a random survey of users with Basset Hounds and Welsh Corgis. Which statement best compares the height of the two breeds based on the collected data?
An adult Welsh Corgi is always going to be shorter than an adult Basset Hound.
Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.
There is no noticeable difference in the height of the two breeds since the Mean Absolute Deviation for each breed is roughly the same.
It is impossible to make a valid conclusion because the sample sizes are too small.
Answer:
An adult Welsh Corgi is always going to be shorter than an adult Basset Hound.
Step-by-step explanation:
That's what I think because the Basset Hound is 13.8 in. in height right? So he's two inches taller if we round up both numbers. Basset hound would be 14 and welsh corgi would be 11....................okay im not sure i give up but it's either
"An adult Welsh Corgi is always going to be shorter than an adult Basset Hound."
"Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.
whichever just not the other ones good luck!
Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.
What is mean?
Mean is actually the average of all the observations.
What is absolute mean deviation?Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.
of a data set is the average distance between each data value and the mean.
How to know which statement best compares the height of the two breeds based on the collected data?According to the problem,
Mean height of Basset hounds is 13.8Mean height of Welsh Corgis is 11.1 Mean absolute deviation of height of Basset hounds is 1.9Mean absolute deviation of height of Welsh Corgis is 1.2Here we can say, the average height of Basset hounds is 13.8 and is highly dispersed in comparison to Welsh Corgis
So, we can say Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.

Answer:
perpendicular
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x = y - 5 ( add 5 to both sides )
3x + 5 = y ← in slope- intercept form
with slope m = 3
------------------------------------------------
9y + 4x = x - 9 ( subtract 4x from both sides )
9y = - 3x - 9 ( divide all terms by 9 )
y = - [tex]\frac{1}{3}[/tex] x - 1 ← in slope- intercept form
with slope m = - [tex]\frac{1}{3}[/tex]
-----------------------------------------------
Parallel lines have equal slopes
The product of the slopes of perpendicular lines = - 1
Thus
the slopes are not equal, thus not parallel lines.
3 × - [tex]\frac{1}{3}[/tex] = - 1 , hence lines are perpendicular
Solve the inequality. Graph the solution.

Distance between the points B= (3,-1) and C= (7,-8) round to the nearest 100
Answer:
8.06
Explanation:
For this question, you have to use the distance formula
Answer:
8.06
Step-by-step explanation:
To find the distance between two points, you would use the distance formula.
The distance formula is:
[tex]\sqrt{(x_2-x_1)^{2}+(y_2-y_1)^{2}}[/tex]
where (x₁, y₁) and (x₂, y₂) are two points.
Lets plug in the points (3, -1) (x₁, y₁) for (7, -8) for (x₂, y₂):
[tex]\sqrt{(7-3)^{2}+((-8)-(-1))^{2}}[/tex]
= [tex]\sqrt{4^{2}+(-7)^{2}}[/tex]
= [tex]\sqrt{16+49}[/tex]
= [tex]\sqrt{65}[/tex]
≈ 8.06225775
Rounded to the nearest hundredth, it is 8.06.
So the distance between the points B and C rounded to the nearest hundredth is 8.06.
I hope you find my answer helpful.

What is the value of x in the equation 3/ 2 ( 4 x − 2 ) − 3 x = 5 − ( x + 2 ) ?
3/2 is a fraction
Answer:
x = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given
[tex]\frac{3}{2}[/tex](4x - 2) - 3x = 5 - (x + 2) ← distribute parenthesis on both sides
6x - 3 - 3x = 5 - x - 2 , that is
3x - 3 = 3 - x ( add x to both sides )
4x - 3 = 3 ( add 3 to both sides )
4x = 6 ( divide both sides by 4 )
x = [tex]\frac{6}{4}[/tex] = [tex]\frac{3}{2}[/tex]
