3(2c + 5) = 39
What is the answer ?
Answers
Answer:
c=1
Step-by-step explanation:
Simplifying
3 + 2c = 5
Solving
3 + 2c = 5
Solving for variable 'c'.
Move all terms containing c to the left, all other terms to the right.
Add '-3' to each side of the equation.
3 + -3 + 2c = 5 + -3
Combine like terms: 3 + -3 = 0
0 + 2c = 5 + -3
2c = 5 + -3
Combine like terms: 5 + -3 = 2
2c = 2
Divide each side by '2'.
c = 1
Simplifying
c = 1
Answer:

Which conic section is represented by the following equation?
5x^2 – x + 5y^2 – 3y + 4 = 0
circle
ellipse
parabola
hyperbola
Answers
Answer:
3 rd one
Step-by-step explanation:
The conic section represented by the given equation is Circle.
What is Circle?Circle is a two dimensional figure which consist of set of all the points which are at equal distance from a point which is fixed called the center of the circle.
Standard form of a circle is,
(x - h)² + (y - k)² = r²
where, (h, k) is the center of the circle and r is the radius of the circle.
Expanding, we get,
x² - 2hx + h² + y² - 2ky + k² = r²
x² - 2hx + y² - 2ky + (h² + k² - r²) = 0
The given equation is,
5x² – x + 5y² – 3y + 4 = 0
This is same as the standard form of the circle.
Hence the given equation is that of a circle.

PLEASE HELP ILL GIVE BIRRELANTIST
Answers
Answer:
A.) 555 in.^2
Step-by-step explanation:
When solving these types of things, I usually like to cut it up into smaller, easier to manage shapes.
You can cut that trapezoid into two triangles and one rectangle.Since both triangles are the same size, you don't need to divide the base and height by two, so you'll get the area of both triangles combined (which saves some work). We know the length of the rectangle and bases of the triangle combined is 44 inches, and that the length of just the rectangle is 30 inches, so we can just subtract 30 from 44 and divide it by two for the base of a triangle.44 - 30 = 14
14/2 = 7
Now that we filled in the information not listed, we can finally solve:
The base of one triangle is 7 inches, and the height is 15 inches.
Now, we just multiple and divide it by 2 for one triangle (it would be 52.5 inches).
But, we don't need to divide it by two because both triangles are the same size, so we can just get the sum of the area of both triangles combined by skipping that step (because triangles are half a square and two of those triangles make a full square).
7 x 15 = 105
The area of both triangles combined: 105 in.^2
Next, we need to solve the area of the rectangle. This is easy considering all you have to do is multiply 15 by 30 (length times width).
15 x 30 = 450
The area of the rectangle: 450 in.^2
Now, the final step. Addition. All you need to do is add up all the sums, and you're done.
450 + 105 = 555
The area of entire figure: 555 in.^2
NOTE: the symbol '^' represents exponents, so when you see 555 in.^2, it means inches squared (or to the power of 2)

You need to download 3 games for your math class. Each game is the same price. Since this is your first time downloading a game from the site, you are also charged a one-time $0.50 access fee. You are charged a total of $4.35. What is the cost of each game? Show your work and round your answer to the nearest cent.
Answers
Answer:
Each game costs $1.28.
Step-by-step explanation:
First, we need to find the total of all the games.
Since the only additive is the $0.50, we simply subtract it from the total.
4.35-0.50=$3.85
Since you bought three games, and they're all the same price, we divide $3.85 by 3.
3.85/3=1.2833333
Since were doing it by pennies, we can round it down to $1.28 per game.
Hope this helps!

A company is analyzing whether its employees prefer to skip their lunch break and leave a half-hour early each day or take a lunch break and
leave at the normal time each day. It conducts an observational study to determine which option is selected more often. At the end of the first
week, the company finds that the majority of employees prefer to skip their lunch break and leave a half-hour early each day.
The company then repeats the observational study for 10 more weeks. The study yields the same results for only five of the weeks. What
generalization can be made from the results of this study?
A.
The majority of employees prefer to take a lunch break and leave at the normal time each day.
В.
The sample is biased; therefore, a generalization cannot be made regarding which option is selected more often.
C.
The results are inconclusive; therefore a generalization cannot be made regarding which option is selected more often.
D.
The majority of employees prefer to skip their lunch break and leave a half-hour early.
Answers
Answer:
C. The results are inconclusive; therefore a generalization cannot be made regarding which option is selected more often.
explanation:
just took the test on plato
Since the study yields the same results for only five of the weeks. So here the generalization could be made like option c.
What type of generalization made?Since at the closing of the first week the company determined the majority of the employees should prefer the lunch break and also the company repeats the observational study for 10 more weeks.
So here the output is to be inconclusive. Due to this, the generalization cannot be made with respect to the selection of the given options.
hence, the option c is correct.

In 5 1/2 hours of driving, Samuel traveled 264 miles. At that rate, how long would it take him to travel 348 miles?
Answers
Answer: It will take Samuel 7 1/4hours to travel 348miles
Step-by-step explanation:
Step 1
Time spent in Driving = 5 1/2 hrs
Distance he drove = 264 miles
There the speed he drove at = Distance / Time
Speed = Distance / =Tme
= 264/ 5 1/2= 264/ 11/2= 264 x 2/ 11=528/11= 48 miles per hour
Step 2
At The same rate of 48miles per hour, it will take him to travel 348 miles
Therefore the time taken = Distance / speed
Time = 348 miles/48 miles per hour
Time=7.25 = 7 1/4 Hours

It’s solving systems of equations
Answers
Answer:
7 quarters, 8 nickels
Step-by-step explanation:
So the system of equations you have is:
x + y = 15
0.25x + 0.05y = 2.15
Here's how to solve:
first, multiply both sides of the equation 0.25x + 0.05y = 2.15 by 100 to get rid of the decimal places:
25x + 5y = 215
Then, you can divide both sides by 5 to simplify it more:
5x + y = 43
Now, you have the system of equations:
5x + y = 43
x + y = 15
Now subtract the two equations:
4x = 28
divide both sides by 4
x = 7
plug x = 7 into the equation x + y = 15 to solve for y:
7 + y = 15
subtract 7 from both sides
y = 8
So you know that there are 7 quarters and 8 nickels.
