solve for x: 3(2x+54)-(27x-3)=56
Answer:
x = 109/21
Step-by-step explanation:
Step 1: Write equation
3(2x + 54) - (27x - 3) = 56
Step 2: Solve for x
Distribute: 6x + 162 - 27x + 3 = 56Combine like terms: -21x + 165 = 56Subtract 165 on both sides: -21x = -109Divide both sides by -21: x = 109/21Can someone please help to explain this to me? I have been trying to work at it and have spent time watching multiple videos trying to figure it out, but am unable to figure it out. Any help would be much appreciated! Thank you.

Wally counted 200 pennies from his piggy bank. He kept 80% of them. How many pennies did Wally keep?
Answer:
I believe he kept 160 pennies.
Step-by-step explanation:
10% of 200 is 20 (200 divided by 10) so 20% is 40 pennies. 200 minus 40 is 160 (pennies)

A square pyramid and cube are shown below. Name the two dimentional figure that is a cross section of the cube but not the pyramid.
Octagon
Square
Triangle
Rectangle
Answer: Square
The cross section of a cube would be a square, because cubes are made of 2D squares. The cross section of a pyramid would be triangles because they are made of a top with triangles.
The answer is square. Hope this helps!
Answer: The answer is Square.
A cube has sides constructed as 2 Dimensional squares. A pyramid has cross sections of triangles, so they do not have the same shape as a cross section. The answer is square.

A student survey was conducted at a major university, and data were collected from a random sample of 750 undergraduate students. One variable that was recorded for each student was the student's answer to the question: "What region of the country did you live in just prior to enrolling in this university? Northeast/Southeast/Northwest/Southwest/Midwest/Outside the U.S." These data would be best displayed using which of the following?
a. Pie Chart
b. Histogram
c. InterQuartile Range
d. Stemplot
e. Boxplot
Answer:
Pie Chart
Step-by-step explanation:
The pie chart is a circular representation of data. It is divided into slices in order to show the distribution of data presented.
In a pie chart, the angle subtended by each slice is proportional to the magnitude of data represented.
Pie charts are most useful in the representation of categorical data such as the region of the country in which a student lived prior to enrolling in the university.
What is the difference of (5 + 3i) and (2 + 9i)?
Answer:
3+12i
Step-by-step explanation:
The difference of 5+3i and 2 + 1999 can be calculated as follows
= 5+3i - 2+9i
Collect the like terms
= 5-2+3i+9i
= 3+12i
Hence the difference of 5+3i and 2+9i is 3+12i

Internet Audience At the end of a certain year, the four companies with the largest number of home Internet users in the United States were Microsoft, Time Warner, Yahoo, and Google, with a combined audience of 284 million users. Taking x to be the Microsoft audience in millions, y the Time Warner audience in millions, z the Yahoo audience in millions, and u the Google audience in millions, it was observed that
z − u = 3(x − y) + 12
x + y = 50 + z + u
and x − y + z − u = 48.
How large was the audience of each of the four companies at the end of that year? Microsoft
Time Warner
Yahoo
Google
Answer:
Microsoft = 89.5 million
Time Warner = 77.5 million
Yahoo = 82.5 million
Google = 34.5 million
Step-by-step explanation:
Given
z − u = 3(x − y) + 12
x + y = 50 + z + u
x − y + z − u = 48.
From the question, we also understand that
u + x + y + z = 284
Required
Solve for u, x, y and z
Substitute 3(x - y) +12 for z - u in the third equation
x − y + z − u = 48.
(x - y) + 3(x - y) = 48
4(x - y) = 48
Divide both sides by 4.
x - y = 12
Make z + u the subject of formula in u + x + y + z = 284
z + u = 284 - (x + y)
Substitute 284 - (x + y) for z + u in the second equation
x + y = 50 + z + u
x + y = 50 + 284 - (x + y)
(x + y) + (x + y) = 50 + 284
2(x + y) = 334
Divide both sides by 2
x + y = 167
Make x the subject of formula
x = 167 - y
Substitute 167 - y for x in x - y = 12
167 - y - y = 12
167 - 2y = 12
-2y = 12 - 167
-2y = -155
2y = 155
y = 77.5
Solve for x in x = 167 - y
x = 167 - 77.5
x = 89.5
Recall that:
z − u = 3(x − y) + 12
z + u = 284 - (x + y)
Substitute the values of x and y in the above expressions.
z − u = 3(x − y) + 12
z - u = 3(89.5 - 77.5) + 12
z - u = 3(12) + 12
z - u = 36 + 12
z - u = 48
Make z the subject
z = 48 + u
Similarly,
z + u = 284 - (x + y)
z + u = 284 - (89.5 + 77.5)
z + u = 284 - 167
z + u = 117
Substitute 48 + u for z
48 + u + u = 117
48 + 2u = 117
2u = 117 - 48
2u = 69
u = 34.5
Substitute 34.5 for u in z = 48 + u
z = 48 + 34.5
z = 82.5
The size of audience of each of the four companies at the end of that year are;
Micro-soft = 89.5 million
Time Warner = 79.5 million
Yah oo = 34.5 million
Goo gle = 82.5 million
We are given the equations;
z − u = 3(x − y) + 12 ----(1)
x + y = 50 + z + u ----(2)
x − y + z − u = 48 ----(3)
Now, we are told that the combined 4 audience is 284 million users. Thus;
u + x + y + z = 284 ----(4)
Put 3(x − y) + 12 for z - u in the eq 3 to get;
(x - y) + 3(x - y) = 48
x - y + 3x - 3y
4x - 4y = 48
Divide both sides by 4 to get;
x - y = 12 ----(5)
Make z + u the subject of formula in eq 4 to get;
z + u = 284 - (x + y) ---(4b)
Put 284 - (x + y) for z + u in the eq 2;
x + y = 50 + 284 - (x + y)
x + y = 334 - x - y
Add x + y to both sides to get;
x + y + x + y = 334
2x + 2y = 334
Divide both sides by 2 to get;
x + y = 167 -----(6)
Add eq 5 to eq 6 to get;
2x = 167 + 12
2x = 179
x = 179/2
x = 89.5
Put 89.5 for x in eq 6 to get;
89.5 + y = 167
y = 167 - 89.5
y = 77.5
Put the values of x and y in eq(1) and eq(4b) to get;
z - u = 3(89.5 - 77.5) + 12
z - u = 48 ---(7)
Also,
z + u = 284 - (89.5 + 77.5)
z + u = 117 ---(8)
Add eq 7 to eq 8 to get;
2z = 165
z = 165/2
z = 82.5
Put 82.5 for z in eq 8 to get;
82.5 + u = 117
u = 117 - 82.5
u = 34.5

What happens to the oxygen released during photosynthesis?
A. The oxygen atoms react with hydrogen atoms and produce water
molecules
B. The oxygen atoms are released from the atmosphere into space.
C. The oxygen atoms diffuse through the atmosphere and are
inhaled by animals.
D. The oxygen atoms diffuse through the atmosphere and are reused
as a reactant for photosynthesis.
Answer:
I believe your answer is C, the oxygen atoms diffuse through the atmosphere and are
inhaled by animals.
Step-by-step explanation:
Plants take in water that later splits to create hydrogen and oxygen. Since plants don't need oxygen, it gets released into the atmosphere for us and other animals to breathe.

Step-by-step explanation:
Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below. Tobias got a score of 74.7; this version has a mean of 61.7 and a standard deviation of 13. Norma got a score of 351; this version has a mean of 291 and a standard deviation of 25. Vincent got a score of 7.38; this version has a mean of 6.9 and a standard deviation of 0.4. If the company has only one position to fill and prefers to fill it with the applicant who performed best on the aptitude test, which of the applicants should be offered the job?
Answer:
Norma performed best on the aptitude test and should be offered the job.
Step-by-step explanation:
We are given that three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below. Tobias got a score of 74.7; this version has a mean of 61.7 and a standard deviation of 13. Norma got a score of 351; this version has a mean of 291 and a standard deviation of 25. Vincent got a score of 7.38; this version has a mean of 6.9 and a standard deviation of 0.4.
Now, to find which of the applicants should be offered the job, we have to find the z-score of each of the applicants, and the one who gets the highest z-score will get the job.
The z-score probability distribution for the normal distribution is given by;
Z = [tex]\frac{X-\mu}{\sigma}[/tex] ~ N(0,1)
where, [tex]\mu[/tex] = mean and [tex]\sigma[/tex] = standard deviation
Firstly, we will find the z-score for Tobias;
The z-score of 74.7 = [tex]\frac{X-\mu}{\sigma}[/tex]
= [tex]\frac{74.7-61.7}{13}[/tex] = 1
Now, we will find the z-score for Norma;
The z-score of 351 = [tex]\frac{X-\mu}{\sigma}[/tex]
= [tex]\frac{351-291}{25}[/tex] = 2.4
Now, we will find the z-score for Vincent;
The z-score of 7.38 = [tex]\frac{X-\mu}{\sigma}[/tex]
= [tex]\frac{7.38-6.9}{0.4}[/tex] = 1.2
As we can clearly see that the z-score is highest for Norma which means that Norma performed best on the aptitude test and should be offered the job.
