Answer:
5. k=−3
6. x=4
7. n=−108
Step-by-step explanation:
5. -14k+29=71
Subtract 29 from both sides
-14k+29-29=71-29
Simplify
-14k=42
Divide both sides by -11
-14k/-14=42/-14
6. -33=19-13x
Subtract 29 from both sides
-14k+29-29=71-29
Simplify
-14k=42
Divide both sides by -14
-14k/-14=42/-14
Simplify
k=-3
7. 8+n/25=-4
Multiply both sides by 25
25(8+n)/25 = 25 (-4)
Simplify
8+n=-100
Subtract 8 from both sides
8+n-8=-100-8
Simplify
n=-108

what is the number that is two more than one-tenth of one-fifth of one-tenth of 2,000
Answers
Answer:
6
Step-by-step explanation:
2 + (1/10)(1/5)(1/10)2000 = 2 + (1/500)(2000) = 2 + 4 = 6
The number that is two more than one-tenth of one-fifth of one-tenth of 2,000 will be 6.
What are the ratio and proportion?The ratio is the division of two numbers while multiplication is an operation in mathematics to multiply two or more values to get a multiplied number.
Proportion is the relation of a variable with another. It could be direct or inverse.
The one-tenth of x = (1/10)x similarly
one-tenth of one-fifth of one-tenth = (1/10)(1/5)(1/10)
So one-tenth of one-fifth of one-tenth of 2,000 = (1/10)(1/5)(1/10) ×2000
⇒ 2000/500 = 4 Now the question is saying 2 more hence
⇒ 4 + 2 = 6 hence six will be the correct answer.

2. The following list of prices is for a used original radio for a 1955 Thunderbird. The prices vary
depending on the condition of the radio.
$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200
a. Find the mean of the radio prices. Round to the nearest cent.
Answers
Answer: $275
Step-by-step explanation:
The mean of the radio price is $275 or 27500 cents
Given,
Price of used original radio for a 1955 Thunderbird:
$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200
We need to find the mean of these prices.
And round to nearest cent.
What is the mean of a set of values?The mean is the average of all the given sets of values.
Example:
1,2,3,4
Mean = (1+2+3+4) / 4 = 10/4 = 2.5
Find the sum
$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200
Sum=(210+210+320+200+300+10+340+300+245+325+700+250+240+200)
Sum = 3850
Find the number of prices.
= 14 prices
Find the mean.
= 3850 / 14
= 275
The mean radio price is $275.
Converting into cents.
$1 = 100 cents
$275 = 27500 cents
Thus the mean of the radio price is $275 or 27500 cents

Answers
Answer:
x = 12, y = 8
Step-by-step explanation:
Since we know that the two triangles are similar that means we can find the ratio. The larger triangle is two times larger, we can find that out using 7/3.5 = 2. That means x + 4 = 2y and 3y = 2x. We can solve for y using substitution. We can double the first equation. 2x + 8 = 4y. We know that 2x = 3y so we can plug that in. 3y + 8 = 4y. Solving for y, gets us y = 8. Now we can plug that into any of the prior equations. I'll use 3y = 2x. 3(8) = 2x. 24 = 2x. Divide both sides by 2. x = 12.

maybe try -5 since the rise/run is 5/1 and the slope is negative
The slope of the graphed line is m = -5
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 0 , 2 )
Let the second point be Q ( 2 , -8 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 2 - ( -8 ) ) / ( 0 - 2 )
m = 10 / -2
m = -5
Hence , the slope is m = -5

What is the product of radical 6 and 10 radical 12 in simplest radical form
Answers
Explanation: We can combine the 6 and 12 because they are both under the radical and get 10√72.
We can simplify the √72 to √(36*2), which becomes 6√2.
We can then multiply the 6 and 10 (both are outside the radical) to get 60√2.

What we should know is how many words he can type in 1/4 minutes. We can do 110 divided by 2.75 which is 40. 40 is the number of words he can type in 1/4 minutes. Now multiply this 17 (4 1/4 = 17/4) and you get 680. I believe he can type 680 words in 4 1/2 minutes. (Make sure my answer is correct)
earth's equator has a diamter of 7926.4 miles. which equation can be used to find the circumference of earth at the equator?
Answers
Answer:
To find the circumference you need to use C= 2πr but since you started with the diameter you need to divide it by 2 and you will get 3963.2. After you get the radius use the formula C= 2πr and you will get 24901.52
The equation would be written as 2 x π x 3963.2 = 24901.52
