n - 6 = -6(n + 4)
Performing the indicated multiplication, we get:
n - 6 = -6n - 24
Combining like terms results in 7n = -18, so n = -18/7

"What is the GCF (greatest common factor) of 60x^3- 10x^2+ 30x?
Answers
Answer:
10x
Step-by-step explanation:
Given the expression 60x^3- 10x^2+ 30x, we are to find the GCF
First let us find the factors of each terms
60x³ = 6 * (10 * x) * x²
10x² = 1 * (10 * x) * x
30x = 3 * (10 * x)
From the three factors, you can see that 10*x is common to them all. Hence the GCF of the expression will be 10x

The number of households without a computer at home in 2009 was closest to A)801000 B)1153000 C)1737000 D)3433000 E)4017000
Answers
Answer:
B) 1153000
Step-by-step explanation:
Given
See attachment
Required
Number of households without computer in 2009
From the attachment, we have:
[tex]n=5170000[/tex] --- survey
[tex]p = 22.3\%[/tex] --- proportion without computer
So, the actual number is:
[tex]Number = p * n[/tex]
[tex]Number = 22.3\% * 5170000[/tex]
[tex]Number = 1152910[/tex]
[tex]Number \approx 1153000[/tex]
Hence: (B) is correct

Give your answer in the form a√b where a and b are integers, and b is as small as
possible.
Answers
Answer:
(√6x√20) / √3 = 2√10
Step-by-step explanation:
hello :
(√6x√20) / √3 =√2x√3 x√4x√5 / √3
because : √6 = √2x√3 and √20= √4x√5 = 2x√5
now simplify by √3 :(√6x√20) / √3 =√2x2x√5
(√6x√20) / √3 = 2√10 so : a =2 and b =10
Surgery Satisfaction Survey
Surgery Satisfied Dissatisfied Total
Knee 70 25 95
Hip 90
15 105
Total 160 40 200
The table shows survey results for 200 patients who had either hip or knee surgery. If one person is selected randomly, what is the
probability he or she was dissatisfied, given that he or she had hip surgery? (Round to the nearest tenth of a percent.)
A)
44.2%
B)
38.6%
0
21.7%
D)
14.3%
Answers
Answer: D) 14.3%
Step-by-step explanation:
Conditional probability formula:
[tex]P(B |\text{given that A}) =\dfrac{P(A\ and\ B)}{P(A)}[/tex]
So, The probability he or she was dissatisfied, given that he or she had hip surgery = [tex]\dfrac{\text{Number of persons are dissatisfied and has hip surgery}}{\text{Total persons have hip surgery}}[/tex]
From the table, the number of persons who are dissatisfied and has hip surgery = 15
Total persons have hip surgery = 105
Required probability = [tex]\dfrac{15}{105}\approx0.143[/tex]
In percent, Required probability = 14.3%
Correct option D) 14.3%

Answers
Answer:

Step-by-step explanation:
Finding a GPA is just like finding an average, you add up all of the different outcomes and divide it by the total amount of outcomes and you will get the average. You also need to know how many points each letter grade is worth. It is normally A=4.0 B=3.0 C=2.0 D=1.0 and F=0. In this case here is what you will add,
3+4+3+2=12
Now that you have the total number of points you need to divide the total by the total outcomes which would be,

Adam writes a number. The number is

What numbers could Adam have
written? Explain.
Answers
Answer:
51, 52, 53
Step-by-step explanation:
51, 52, and 53 are all greater than 50, but less than 54
The possible numbers that Adam could have written are any number between 50 and 54, such as 51, 52, or 53.
What is the number system?Number systems are mathematical systems that are used to express numbers in various ways.
Given that the number is "greater than 50 and less than 54", which means it must be strictly between those two values.
Here, the range of numbers that Adam could have written is (50, 54), which means any number greater than 50 and less than 54, but not including 50 and 54 themselves.
Thus, the possible numbers that Adam could have written are any number between 50 and 54, such as 51, 52, or 53.

WHAT DOES THIS MEAN GIMME THE ANSWER
Answers
Answer:
This is a geometric sequence and the ratio is equal to 4.
Step-by-step explanation:
Arithmetic means you can continue the sequence through addition or subtraction.
Geometric means you can continue the sequence through multiplication or division.
To get from 3 to 12, we could either add 9 (arithmetic) or multiply by 4 (geometric).
To get from 12 to 48, we could either add 36 or multiply by 4.
Since we are looking for a pattern, the sequence would be geometric. This is because the sequence can be continued by multiplying by 4 each time. It cannot be arithmetic because we cannot add by 9 each time.
On a side note, common difference is used when describing arithmetic while ratio is used to describe geometric.

b)lets say the area of the map is 21 square inches. you want to make q enlarged map of central park to take with you on your journey. describe how you can determine the area of the the enlarged map.
c)supposed the scale factor you will ise to enlarge the map is 5:1. what is the approximate area of the park of the park in your enlarged drawing.
d) how did you apply proportional reasoning as you worked through these problems?
Answers
it is either the second one or the last one
Answer:
For (a) the answer is 450, 50(9)=450 total blocks.
Step-by-step explanation:
For (c), you will have to use a scale of 1 to 5, so, 450(5)=2,250.
For (b), if the map is 21 square inches and you want to enlarge it to the size you want, you would have to take the total value of the original map and multiply it by whatever factor it has to be multiplied by.
Now finally for (d), I applied proportional reasoning by looking at the dimensions and adding them all together to get the area value, then comparing the area value to the enlarged figure or decreased figure.
