Answer:
-16n - 41
Step-by-step explanation:
To simplify the equation, you need to get rid of the parentheses by multiplying the numbers outside the parentheses to the numbers inside. Then, you can combine the similar terms.
2(-n - 3) - 7(5 + 2n) <---- Original equation
-2n - 6 - 7(5 + 2n) <---- Expand first parentheses by mult.
-2n - 6 - 35 - 14n <---- Expand second parentheses by mult.
-16n - 6 - 35 <---- Combine terms with "n"
-16n - 41 <---- Combine whole numbers
Answer:-2n-29
Step-by-step explanation:2*-n=-2n
2*-3=-6
-7*5=35
-7*2n=-4n
2n-6-35-44n
2n-4n=-2n
6-35=-29
2n-29

This composite figure is made up of three simpler shapes. What approximate area of the figure use 3.14 for Pi. A,B,Cor D?
Answer:
B. 24.28 square feet
Step-by-step explanation:
To find the area of the entire composite figure, you will want to find the area of each shape in it and add them up. Personally, I like to start with the easiest one so in this case I would start with the rectangle.
To find the area of the rectangle, you must multiple length and width (l × w or b × h). So you would multiple 4ft by 3ft in this problem. The area of the rectangle then is 12 squared feet (12 ft²).
Next, find the area of the triangle using the formula 1/2×b×h (base= b; height= h). This is because since triangles are basically just squares and rectangles cut in half, all you would do it do the extra step of multiplying it by 1/2. In this problem, after substituting, you would get 1/2(4)(3). The area of the triangle then is 6 squared feet (6 ft²).
Finally, you want to find the area of the semi-circle. To do so, you must use the formula for finding the area of a circle which is π(r)². It is important to pay attention to what is given in the problem because of including the wrong number in your calculations.
In this problem, you are given the diameter of a circle, but what you need is the radius (per the circle area formula) so all you need to do it half it.
Diameter= 2r or Radius = 1/2D
This gives you the fact that the radius of a circle from this problem is 2 because the diameter is 4. HOWEVER, you need to remember that this problem is not asking you to include the area of a circle, it is asking for a semi-circle. This means that you would have to half the answer you get.
There are two easy ways of doing so for this case like:
1/2 π(2)² 1/4 π (2)²
Just plug either equation into the calculator and have it solved to have the area of the semi-circle.
The last and easiest step is just adding all 3 areas calculated to get the approximate total area of the figure!

After y – 4x = 12 is put in slope-intercept form, what is the slope?
-4
1/4
-3
4
Answer:
Slope is 4.
Step-by-step explanation:
The slope-intercept form is y=mx+b
We have to move the -4x over to create a slope-intercept equation.
∴ y=4x+12
Since m=4, the slope would be 4.
Answer: 4
Step-by-step explanation:
First, you have to arrange the equation in the correct way so that you will be able to get the slope. when -4x is shifted to the other side in order to make y the subject -4x will become +4x, so then it is obvious that the slope is 4! yay!

Use the following images to answer the question:
a. Write a truth statement about each picture using Euclidean postulates.
b. Write the matching Euclidean postulate.
c. Describe the deductive reasoning you used.
Truth statement are statements or assertions that is true regardless of whether the constituent premises are true or false. See below for the definition of Euclidean Postulates.
What are the Euclidean Postulate?
There are five Euclidean Postulates or axioms. They are:
1. Any two points can be joined by a straight line segment.
2. In a straight line, any straight line segment can be stretched indefinitely.
3. A circle can be formed using any straight line segment as the radius and one endpoint as the center.
4. Right angles are all the same.
5. If two lines meet a third in a way that the sum of the inner angles on one side is smaller than two Right Angles, the two lines will inevitably collide on that side if they are stretched far enough.
What are the truth statements relating to the pictures and their equivalent Euclidean Axiom?The right angle in the first page of the book shown and the right angles in the last page of the book shown are all the same. (Axiom 4);If the string from the Yoyo dangling from hand in the picture is rotated for 360° such that the length of the string remains equal all thought, and the point from where is is attached remains fixed, it will trace a circular trajectory. (Axiom 3)The swords held by the fighters can be extended into infinity because they are straight lines (Axiom 5)Learn more about Euclidean Postulates at:

Answer: Volume = 97.6
Step-by-step explanation:
Volume of the cone first
V = 1/3 h π r²
h = 0.7
r = 2
V = 1/3 × 0.7 × 2² × 3.14
V = 1/3 × 0.7 × 4 × 3.14
V = 1/3 × 8.792
V = 2.93
Then find the volume of the cylinder if the cone was there.
V = π r² h
r = 2
h = 8
V = 3.14 × 2² × 8
V = 3.14 × 4 × 8
V = 3.14 × 32
V = 100.48
Now you subtract the volume of the cone from the cylinder.
100.48 - 2.93 = 97.55
Rounded to the nearest tenth is 97.6

Find an equivalent ratio where the total number of games is 100
Wins: 3
Total games: 12. 100
Answer: 25
Step-by-step explanation:
3 x
__ = ___
12 100
If 3 games were won out of a total of 12, we can use this number to determine about how many wins would happen if the total were 100.
We can cross mulltiply with the proportion above:
12x= 300
x= 25
Another method we can use is to use the probability. In other words, 3/12 wins= a probability of 1/4. When they ask how many out of something can be found using an outcome from a previous event, multiply that event by the new number, or 100.
1/4 of the games were won when the total was 12, so out of 100, we can do:
1/4 of 100 = 25.
25 wins expected
Hope this helps :)
Write an equation to represent the cost ordering balloons from Balloons-R-Fun.
You and your friends are considering having balloons delivered to your favorite teacher on the last day of school. Ballons-R-Fun charges $1.25 per balloon and $6 delivery fee. Singing Balloons charges $1.45 per balloon and $2 for delivery fee. Use a system of equations to calculate what the cost will be if you ordered the same number of balloons from either service.
Ballons-R-Fun:
cost=(n x 1.25) + 6
Singing Balloons:
cost=(n x 1.45) + 2
* n = number of balloons
If this equation is used:
eg. 5 balloons were order.
Ballons-R-Fun:
cost=(n x 1.25) + 6
cost=(5x1.25) + 6
cost=12.25
Singing balloons:
cost=(n x 1.45) + 2
cost=(5x1.45) + 2
cost=9.25
therefore = singing balloons are cheaper.
