Answer:
9+x=14
Step-by-step explanation:
The x represents the other sister and all the books together would equal 14. The other sister got 5 books!
The equation that represents the number of books bought by the other sister is x + 9 = 14.
Here, we have,
given that,
Two sisters bought together 14 books. One bought 9 books.
To represent the number of books bought by the other sister (x) given that the two sisters bought together 14 books and one sister bought 9 books, we can use the equation:
x + 9 = 14
In this equation, x represents the number of books bought by the other sister.
The equation states that the sum of the number of books bought by the other sister (x) and the sister who bought 9 books is equal to the total number of books bought together, which is 14.
Therefore, the equation that represents the number of books bought by the other sister is x + 9 = 14.

What is the measure of ∠ABD?
Answer:
m∠ABD = 114°
Step-by-step explanation:
Given measurements of interior angles are:
m∠D = 2n°
m∠C = 60°
m∠ABD = (4n+6)°
The measurement of exterior angle of a triangle is equal to the sum of two opposite interior angles.
This can be mathematically expressed as:
m∠ABD = m∠C+m∠D
Putting the respective values
[tex]4n+6 = 2n+60\\4n-2n+6 = 60\\2n+6 = 60\\2n = 60-6\\2n = 54\\\frac{2n}{2} = \frac{54}{2}\\n = 27[/tex]
Putting n=27 in (4n+6)°
[tex]=4(27) + 6\\= 108+6 = 114[/tex]
Hence,
m∠ABD = 114°

An exterior angle of a triangle is 152°. If the non-adjacent angles are congruent, then what are the measures of all of the interior angles of the triangle?
a. 62°, 59°, 59°
b. 90°, 45°, 45°
c. 152°, 14°, 14°
d. 28°, 76°, 76°
9514 1404 393
Answer:
d. 28°, 76°, 76°
Step-by-step explanation:
The sum of the "non-adjacent" interior angles of the triangle is equal to the exterior angle, so is 152°. If those angles are congruent, each is half of 152°, or 76°. The remaining angle is the supplement to 152°, so is 180-152 = 28 degrees.
The interior angles are 28°, 76°, 76°.

Answer:
The answer is C. 16.65 Hope that helps :)
45 percent of 37 is equal to 16.65. The correct answer is C) 16.65.
To find 45 percent of 37, we can multiply 37 by 0.45 since 45 percent is equivalent to 0.45 as a decimal.
37 * 0.45 = 16.65
Therefore, 45 percent of 37 is equal to 16.65.
The correct answer is C) 16.65.
The calculation represents taking 45 percent (or 0.45) of the value 37, resulting in the product 16.65. This means that if you were to take 45 percent of 37, you would obtain the value 16.65. It's essential to understand how to convert percentages to decimals to perform accurate calculations involving percentages.

Determine if the figure below has rotational symmetry, line symmetry or both and
describe the transformation that mas the figure onto itself. BE SPECIFIC. You must
name the center of rotation and degree of rotation if it has rotational symmetry or
lines of reflection if it has line symmetry
Answer:
A) Given that the figure is a rectangle, it has a rotational symmetry and by rotating the figure 180° about the center of the figure, the preimage and image will coincide
The figure also has a line symmetry for the vertical line x = 5, and a line symmetry for the horizontal line y = 5
Therefore the figure has both symmetry
B) The transformation that maps the figure unto itself are therefore;
1) Rotating the figure 180° about the point (5, 5) which is the center of the figure
2) Reflection of the figure across the line x = 5 and also reflection of the figure across the line y = 5

Given:
Jim stands on a dock that is [tex]3\dfrac{3}{4}[/tex] feet above the lake. He dives down [tex]12\dfrac{1}{2}[/tex] feet below the dock.
To find:
The Jims vertical location relative to the lake surface.
Solution:
We have,
Vertical location of dock relative to the lake surface [tex]=3\dfrac{3}{4}[/tex] feet
He dives down [tex]12\dfrac{1}{2}[/tex] feet below the dock. So,
Vertical location relative to the lake surface [tex]=3\dfrac{3}{4}-12\dfrac{1}{2}[/tex]
[tex]=\dfrac{3\times 4+3}{4}-\dfrac{12\times 2+1}{2}[/tex]
[tex]=\dfrac{12+3}{4}-\dfrac{24+1}{2}[/tex]
[tex]=\dfrac{15}{4}-\dfrac{25}{2}[/tex]
Taking LCM, we get
[tex]=\dfrac{15-50}{4}[/tex]
[tex]=\dfrac{-35}{4}[/tex]
[tex]=-8\dfrac{3}{4}[/tex]
Here, negative sign means Jim location is below the lake surface.
Therefore, Jim is [tex]8\dfrac{3}{4}[/tex] feet below the lake surface.

can someone find the slope and y intercept ?
Answer:
Slope = -5/4
Y-Intercept = (0, -4)
Step-by-step explanation:
Step One: Determine two points.
In order to find slope, we have to find the amount of horizontal units (left and right) and vertical units (up and down) that two points are apart. We can choose any two points along this line to compare, so I'll use (0, -4) and (5, 0) since they align perfectly on the grid.
Step Two: Find the difference between the two points.
To find the differences, all we have to do is subtract the second point's X value from the first point's X value. So in this case, we would subtract 5 from 0, which gives us -5.
Next, we have to find the difference in our Y values, so we'll do the same thing here. We'll have 0 - (-4) (or 0 + 4, since subtracting a negative number is technically just addition), which ends up being 4.
Step Three: Put the differences into slope form.
Our slope form is Y/X, or you can think of it as "Rise/Run". We remember that our Y difference was -5, and our X difference was 4, so our end slope would be -5/4.
Step Four: Find the Y-Intercept
Since you have access to a graph of the line, the easiest way is to look at your graph and find the point where the line crosses the Y-axis (the black, vertical line where X = 0). From the graph, we can tell that the blue line crosses the Y-axis at (0, -4), so our Y-Intercept would be (0, -4)
