Answer:
x = 5
Step-by-step explanation:
4x + 2y + z = 24
2x - 3y - z = 2
5x + y + 2z = 21
-----------------
Eliminate z
Add the 1st and 2nd eqn
4x + 2y + z = 24
2x - 3y - z = 2
----------------
6x - 1y = 26 eqn A
Multiply the 2nd eqn by 2, then add the 3rd.
4x - 6y -2z = 4
5x + y + 2z = 21
----------------
9x - 5y = 25 eqn B
---------------
Now you have 2 eqns in 2 unknowns, not 3.
Multiply eqn A by 5 and subtract eqn B.
30x - 5y = 130 eqn A times 5
9x - 5y = 25 eqn B
-------------
21x = 105
x = 5
Answer:
x = 5 is the answer

Part 1: Collect Data
In order to complete your assignment, you will need to collect some data.
The first five data points have been provided for you.
Age
(years) Number of U.S. States Named in 60 Seconds
5 7
15 42
25 49
35 35
65 50
Take a survey of at least five more people. You need a watch, stopwatch, or timer.
First, record the age of the person you are surveying.
Next, ask the person to name as many U.S. states as possible in 60 seconds. Keep a count, and watch your timer. Record each person’s data next to his or her age.
Repeat this with at least five people, and be sure to survey a range of ages, from young to old.
Part 2: Organize Your Data
Create a table of values using the age and number of U.S. states named in 60 seconds.
A graph is provided with the first five points plotted. Use your table to add your five data points to the scatter plot.
You may create a new graph from scratch, containing all 10 points, print the sample graph and add your data, or save the sample as an image and use a drawing program to add your data to the image. If you choose to print and draw by hand, you need to be able to scan and upload your work at the end of the project.
A coordinate plane is shown. The x axis is labeled age in years and the y axis is labeled number of U.S. States named in 60 seconds. Five data points are already plotted on the graph. These points are located at 5 comma 7, 15 comma 42, 25 comma 49, 35 comma 35, and 65 comma 50.
Draw a line of best fit through your scatter plot. Draw by hand on your printed graph or use a drawing program on your computer to create the line.
Part 3: Drawing Conclusions
How did you decide where to place your line of best fit? Describe your reasoning.
Based on your data, describe the relationship between age and the number of U.S. states a person can name in 60 seconds.
Do you see any areas in your data or points that could be considered clusters or outliers? Explain your answer in complete sentences.

What is the perimeter of the triangle?
units
Answers
Answer:
36 units
Step-by-step explanation:
there is 12 units at is base and 9 as its height
you have to use the Pythagorean theorem to find the hypotenuse
c= √(a^2+b^2)( be being 12 and a 9)
plug it in and get c=√(81+144)=√225=15
perimeter is a+b+c
now that we have c do 12+15+9

Three ropes of length 2 m 84 cm, 4 m 26 cm and 7 m 10 cm are to be cut into small pieces of equal length. What is the greatest possible length of each equal part, so that there is no wastage? How many pieces are there in total?
Answers
The greatest possible length of each piece is 2 cm.
What is HCF?The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.
Three ropes of length 2 m 84 cm, 4 m 26 cm, and 7 m 10 cm are to be cut into small pieces of equal length.
We have been given the lengths of the ropes as
2 m 84 cm = 284cm
4 m 26 cm = 426cm
7 m 10 cm= 710 cm
We have to determine the greatest possible length of each equal part So that there is no wastage
So the greatest possible length of each piece will be the HCF of the length of the ropes.
⇒ 284 = 2× 142
⇒ 426 = 2 × 213
⇒ 710 = 2 × 355
Hence, the HCF of the 284, 426, and 710 is 2.
Therefore, the greatest possible length of each piece is 2 cm.

Answer:
Step-by-step explanation:
Circumstance of a curcle C=2*pi*r
So if you want to find r from this equation you come up with r=C/2*pi. That's exactly what they give you in the problem.
Now you know that C= 26.69 so replacing what we know in the formula r=C/2*pi you get
r=26.69/2*3.14 =4.25
So looking at the figure you they said r=4.25
That means that the figure is has to be a circle.
Hope that makes sense.

What is the volume of rectangular prism?The volume of a rectangular prism is defined as the total space occupied by the rectangular prism. The volume of a rectangular prism formula is obtained by multiplying the length, breadth and height of the prism.
One pound price after markup = 1.50 (1 + 10%) = $1.65
The volume of the container = length × width × height
= 10 × 6 × 7
= 420 [tex]in^{3}[/tex]
The final selling price
= 1.65 × 420 × 48
= $33264
Hence, selling price of cat litter in the container shown when the markup is 10% is $33264.
