Problem 10 / (Second Session 2006)
To buy two copybooks and one pen we must pay 2750 L. L, and to buy four copybooks and three pens we must
pay 7750 L. L. The preceding information is translated into the following system:(2x+y=2750
14x + 3y = 7750
1. What does x and y represent in this system?
2. Which information is translated by the equation 4x + 3y = 7750?
3. Solve the preceding system, showing the followed steps in detail, to find the price of a copybook and the price of a pen.
Answer:
Find other solutions in explanation
x = 250
y = 1750
Step-by-step explanation:
x = cost per copybook
y = cost per pen
2. Sum of the cost of 4 copy books and 3 pen is equal to 7750
3.)
2x+y=2750 - - (1)
4x + 3y = 7750 - - - (2)
From (1)
y = 2750 - 2x
Substitute y = 2750 - 2x into (2)
4x + 3(2750 - 2x) = 7750
4x + 8250 - 6x = 7750
-2x = - 500
x = 500/2
x = 250
y = 2750 - 2(500)
y = 2750 - 1000
y = 1750

What expressions has a value equal to 28 divided by 4
Answer:
28/4=28/7
Step-by-step explanation:
when you divide 28 by 4 you get seven so if you use 7 instead of 4 to divide it's an equal value.
Sorry if it's incorrect, there wasn't a whole lot to go by! Good luck tho! :D
An expression that has a value equal to 28 divided by 4, is 7.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
Given:
A phrase: A value equal to 28 divided by 4.
That means,
An expression has a value equal to 28 divided by 4,
28/4,
= 7
Therefore, 7 is the required expression.

Suppose there is 1.4 a drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 64.2, what will be the temperature when the plane reaches an altitude of 8000?
Answer:
The temperature will be 53
Step-by-step explanation:
Here, we are told that there is a temperature drop for every 1000 feet rise into the sky
Now, for 8000 ft, there will be 8 drops
Each drop is 1.4;
So 8 drops will be 1.4 * 8 = 11.2
So to get the current temperature, we simply go on to subtract from what we had initially
Mathematically, that will be
64.2 - 11.2 = 53
A 5 inch x 7 inch photograph is placed inside a picture frame. Both the length and width of the frame are 2x inches
larger than the width and length of the photograph. Which expression represents the perimeter of the frame?
Answer:
Perimeter = 28 + 8x inches
Step-by-step explanation:
Length of the photograph = 7 inches
Width of the photograph = 5 inches
Both the length and width of the frame are 2x inches larger than the width and length of the photograph.
Length of the frame = 7 inches + 2x inches
Width of the frame = 5 inches + 2x inches
Perimeter of the frame = 2(Length + width)
= 2{(7+2x) + (5+2x)}
= 14 + 4x + 10 + 4x
= 28 + 8x inches
Perimeter = 28 + 8x inches

Solve for the y intercept and then for the x intercept .
x-2y=8
**ALSO DON’T ANSWER IF YOU WONT SHOW YOUR STEPS ****
Answer:
x intercept is 8
y intercept is 4
Step-by-step explanation:
x-intercept -> format is (x, 0)
We know that y=0, so we can substitute that in and solve for x to find the x-intercept. x-2y = x - 2(0) = x = 8. Therefore, the x-intercept is 8.
y-intercept -> format is (0, y)
We know that x=0, so we can substitute that in and solve for y to find the y-intercept. x-2y = 0 - 2y = 2y = 8 -> y =4. Therefore, the y-intercept is 4.
I hope this helps! :)

Which graph shows a dilation?
Based on the given graphs, the graph that shows a dilation is the fourth graph.
How to show dilation?When a shape is dilated, it means that a certain figure is used to reduce the shape's dimensions such that it becomes smaller. This certain figure is known as the scale factor.
When a dilation happens, the only thing that changes is the size of the shape. The orientation of the shape remains the same and so does the shape itself.
From this, we can tell that the graph that shows a dilation is the last graph which shows a dilation because the shape becomes smaller but remains the same otherwise.

A pyramid has a side length of 35 meters and the height of the pyramid is 22 meters What measurement is closest to the volume of the pyramid in cubic meters
Answer:
8983 m³
Step-by-step explanation:
The volume of a pyramid is :
[tex]V = \dfrac{s^2 h}{3}[/tex]
where;
s = length of the side
h = height
[tex]V = \dfrac{35^2 \times 22}{3}[/tex]
[tex]V = \dfrac{26950}{3}[/tex]
V = 8983.33
The measurement closest to the volume is approximately 8983 m³

what is the slope of (5,7) and (-2,0)
Answer:
Slope: 1
Step-by-step explanation:
In this question, we need to find the slope with the given points.
To find the slope, we would use the equation:
m = y2-y1/x2-x1
Plug in your coordinates and solve:
m = 0 - 7/-2 - 5
m = -7/-7
Two negatives cancel each other to make a positive, and 7/7 = 1
m = 1
This means that the slope would be 1.
Step-by-step explanation:
(5,7)=(X1,Y1)
(-2,0)=(X2,Y2)
slope(m)=y2-y1/x2-x1
=0-7/-2-5
=-7/-7
=canceled each other then answer is 1

Which table represents a direct variation? Table A x 4 6 8 10 y 7 9 11 13 Table B x 4 6 8 10 y 12 18 24 30 Table C x 4 6 8 10 y 1 3 5 7 Table D x 4 6 8 10 y 3 3 3 3 Table A Table B Table C Table D
Answer:
We conclude that 'Table B' represents a direct variation.
Step-by-step explanation:
We know that when y varies directly with x, the equation is
y ∝ x
y = kx
k = y/x
where 'k' is called the constant of proportionality.
Table A
x 4 6 8 10
y 7 9 11 13
Finding k for all the pairs of x and y
k = y/x
k = 7/4, k = 9/6 = 3/2, k = 11 / 8, k = 13/11
As constant of proportionality 'k' does not remain constant.
Hence, table A does not represent a direct variation
Table B
x 4 6 8 10
y 12 18 24 30
Finding k all the pairs of x and y
k = y/x
k = 12/4 = 3, k = 18/6 = 3, k = 24/8 = 3, k = 30/10 = 3
As the constant of proportionality remains constant.
Therefore, the value of k = 3 for all the points in the table.
Hence, table B represents a direct variation.
Table C
x 4 6 8 10
y 1 3 5 7
Finding k all the pairs of x and y
k = y/x
k = 1/4, k = 3/6 = 1/2, k = 5/8, k = 7/10
As the constant of proportionality 'k' does not remain constant.
Hence, table C does not represent a direct variation.
Table D
x 4 6 8 10
y 3 3 3 3
Finding k all the pairs of x and y
k = y/x
k = 3/4, k = 3/6, k = 3/8, k = 3/10
As the constant of proportionality 'k' does not remain constant.
Hence, table D does not a direct variation.
Therefore, we conclude that 'Table B' represents a direct variation.

It's Table B

A scale has a percent error of 6%. The scale reads the mass of a book as 600 g. Which statement describes what the actual mass of the book could be? The actual mass of the book is either 300 g or 900 g. The actual mass of the book is either 564 g or 636 g. The actual mass of the book is either 594 g or 606 g. The actual mass of the book is either 550 g or 610 g. HELP ASAP FIRST TO ANSWEAR GET BRANLYIEST 20 POINTS
Answer:
between 564 gr and 636 gr
Step-by-step explanation:
If the percent error is 6% (0.06 in decimal form) of 600 gr, then the error is :
0.06 * 600 gr = 36 gr
Therefore the actual mass of the book is between 600 - 36 = 564 gr and 600 + 36 = 636 gr.
Answer:
between 564 grams and 636 grams
