The sum of 10 and a number n, how would you write this a equation ?
Answers
Answer: 10 + n
Step-by-step explanation:
10 and a number are to be added.
The number is denoted as n.
The expression will therefore be:
= 10 + n
In the expression above, n is being added to the number 10 so is the correct equation.

Beth Ann practiced piano for 1 hour 5 minutes each day for 1 week. She had 5 songs to practice and spent the same amount of time practicing each song. How long did she practice each song during the week?
Answers
Answer:
91 minutes per song in a week
Step-by-step explanation:
1 hour 5 minutes each day = 65 minutes per day
Total time spent on practicing piano in a week = 7 × 65 minutes
= 455 minutes
She had 5 songs to practice and spent the same amount of time practicing each song
Amount of time to practice each song = Total time spent on practicing piano in a week / number of songs
= 455 minutes / 5
= 91 minutes per song in a week
Equivalent to 1 hour 31 minutes

1) -15+4r=-9
2)5-y/3=-1
3)42=5x-8
That's all, you don't have to show work, but I'd appreciate it:) asap pls
Answers
Equation #1:
-15+4r=-9We move all terms to the left:
-15+4r-(-9)=0
We add all the numbers together, and all the variables
4r-6=0
We move all terms containing r to the left, all other terms to the right
4r=6
r=6/4
r=1+1/2
Equation #2:
5-y/3=-1We move all terms to the left:
5-y/3-(-1)=0
We add all the numbers together, and all the variables
-y/3+6=0
We multiply all the terms by the denominator
-y+6*3=0
We add all the numbers together, and all the variables
-1y+18=0
We move all terms containing y to the left, all other terms to the right
-y=-18
y=-18/-1
y=+18
Equation #3:
Simplifying
42 = 5x + -8
Reorder the terms:
42 = -8 + 5x
Solving
42 = -8 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
42 + -5x = -8 + 5x + -5x
Combine like terms: 5x + -5x = 0
42 + -5x = -8 + 0
42 + -5x = -8
Add '-42' to each side of the equation.
42 + -42 + -5x = -8 + -42
Combine like terms: 42 + -42 = 0
0 + -5x = -8 + -42
-5x = -8 + -42
Combine like terms: -8 + -42 = -50
-5x = -50
Divide each side by '-5'.
x = 10
Simplifying
x = 10

1/2 = q + 2/3
and
p - 3 1/6 = -18.73
please help, im giving 20 points
Answers
Answer:
see below
Step-by-step explanation:
1/2 = q + 2/3
Subtract 2/3 from each side
1/2 -2/3 = q+2/3-2/3
Getting a common denominator of 6
3/6 - 4/6 = q
-1/6 =q
p - 3 1/6 = -18.73
Add 3 1/6 to each side
p - 3 1/6 + 3 1/6 = -18.73 + 3 1/6
p = -18 73/100 + 19/6
Get a common denominator
p =- 5619/300 + 950/300
= -4669/300
=-15 169/300

Answer:
x = 25
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 3 when x = 15
3 = 15k ( divide both sides by 15 )
\(\frac{3}{15}\) = k, that is k = \(\frac{1}{5}\)
y = \(\frac{1}{5}\) x ← equation of variation
When y = 5 , then
5 = \(\frac{1}{5}\)x ( multiply both sides by 5 to clear the fraction )
25 = x

An angle is an undefined term in plane geometry.
The vertex of \(\angle 4\) is B The sides of \(\angle 1\) are BC and BD Another name for\(\angle 5\) is \(\angle DBE\) \(\angle FBC\)is a right angle \(\angle EBF\) is an obtuse angle \(\angle ABC\) is a straight angle.\(\angle EBC = 144\)\(\angle ABF = 13.5\)I've added as an attachment, the image of the complete question.
Vertex of \(\angle 4\)
The vertex of an angle is the point where the rays that form the angle meet.
From the diagram, rays BE and BA meet at point B to form \(\angle 1\).
Hence, B is the vertex
Sides of \(\angle 1\)
The sides of an angle are the rays that form the angle
\(\angle 1\)is formed by rays BC and BD
Hence, the sides are BC and BD
Another name for \(\angle 5\)
An angle is named by combining the two sides and a vertex.
The sides of \(\angle 5\) are DB and BE,The vertex is B
This means that rays meet at point B
Hence, another name is \(\angle DBE\)
Classify the angles
Angles are classified based on their value
\(\angle FBC\) is a right angle, because \(\angle FBC = 90^o\) \(\angle EBF\) is an obtuse angle because \(\angle EBF\) is greater than \(90^o\) but less than \(180^o\) \(\angle ABC\) is a straight angle, because \(\angle ABC =180^o\)
Angle bisector
Ray BE is an angle bisector, because it divides \(\angle DBA\) into two equal halves.
Find \(\angle EBC\)
We have:
\(\angle EBD = 36\)
\(\angle DBC = 108\)
So:
\(\angle EBC = \angle EBD + \angle DBC\)
\(\angle EBC = 36 + 108\)
\(\angle EBC = 144\)
Find \(\angle ABE\)
We have:
\(\angle EBF = 117\)
\(\angle DBC = 108\)
So:
\(\angle EBF = \angle ABE + \angle EBD + \angle ABF\)
Where
\(\angle ABF = 90\)
\(\angle ABE = \angle EBD\)
So:
\(117 = \angle ABE + \angle ABF + 90\)
\(117 = 2\angle ABF + 90\)
Subtract 90 from both sides
\(27 = 2\angle ABF\)
Divide through by 2
\(\angle ABF = 13.5\)

What is linear model?
Depending on the context, the phrase "linear model" is used differently in statistics. The word is frequently used interchangeably with a linear regression model since it occurs most frequently in relation to regression models. The phrase has a different connotation when employed in time series analysis, though.
The points on the regression line are (2006,184.6), (2007,186.9), (2008,188.5), (2009,189.7), (2010,190.7),(2011,191.5).
The equation of the model is y = 1.35x - 256.
The points on the regression line are (6,184.6), (7,186.9), (8,188.5), (9,189.7), (10,190.7),(11,191.5).
The equation of the model is y = 1.35x + 177.2
The difference between 2016 and 2006 is 10.
Putting x = 10 in the equation y = 1.35x + 177.2:
y = (1.35 × 10) + 177.2
y = 190.7

eleanor scores 680 on the sat mathematics test. the distribution of sat scores is symmetric and single-peaked, with mean 500 and standard deviation 100. gerald takes the american college testing (act) mathematics test and scores 27. act scores also follow a symmetric, single peaked distribution - but with mean 18 and standard deviation 6. find the standardized scores for both students. assuming that both tests measure the same kind of ability, who has the higher score?
Answers
Eleanor's standardized SAT score is 1.8, and Gerald's standardized ACT score is 1.5. Eleanor has the higher standardized score.
To find the standardized scores for Eleanor and Gerald, we use the formula for standardizing a score:
Standardized score = (observed score - mean) / standard deviation
For Eleanor's SAT score:
Standardized score = (680 - 500) / 100
Standardized score = 1.8
For Gerald's ACT score:
Standardized score = (27 - 18) / 6
Standardized score = 1.5
The standardized score measures how many standard deviations an individual's score is from the mean. A standardized score of 0 represents the mean, positive scores indicate above-average performance, and negative scores indicate below-average performance.
Comparing the standardized scores, we see that Eleanor has a standardized score of 1.8, while Gerald has a standardized score of 1.5. Since higher standardized scores indicate better performance relative to the mean, Eleanor has the higher score.
Based on the standardized scores, Eleanor has the higher score compared to Gerald. However, it's important to note that the SAT and ACT scores cannot be directly compared since they have different scales and distributions. The standardized scores allow for a relative comparison within each test, but they do not indicate absolute superiority across different tests.
