Solve the equation: x-10 - 2x + 7 = 8 + x - 10 - 3x
Answer: If you're looking for the value of x, it's 1.
Step-by-step explanation:
Add the numbers. x-10-2x+7=8+x-10-3x--->x-3-2x=8+x-10-3x
Combine like terms. x-3-2x=8+x-10-3x ---> -x-3=8+x-10-3x
Subtract the numbers.-x-3=8+x-10-3x---> -x-3=-2+x-3x
Combine like terms. -x-3=-2+-3x---> -x-3=-2-2x
Rearrange terms. -x-3=-2-2x---> -x-3=-2x-2

a frequency distribution shows the number of observations for each class (class being a value or a range of values), and a relative frequency distribution shows how close the values are to each other.
A frequency distribution shows the number of observations for each class (class is a value or a range of values), and a relative frequency distribution shows how close the values are to each other: TRUE
What is a frequency distribution?
In statistics, a frequency distribution is a graph or data set that shows the frequency of occurrence of each possible outcome of a repeatable event observed many times. Election results and test scores listed by percentile are simple examples. A frequency distribution can be represented graphically as a histogram or a pie chart. The number of observations for each class is shown in a frequency distribution (class is a value or a range of values).What is a relative frequency distribution?
A relative frequency distribution, which is related to a probability distribution and is widely used in statistics, shows the proportion of the total number of observations associated with each value or class of values. The relative frequency distribution demonstrates how close the values are to one another.Therefore, the statement "a frequency distribution shows the number of observations for each class (class is a value or a range of values), and a relative frequency distribution shows how close the values are to each other" is TRUE.

Which of the following is equivalent to −3(2x + 5y) − 7(2q + 3p)? −6x − 15y − 14q − 21p −6x + 5y − 14q + 3p −6x + 15y − 14q + 21p −21(2x + 5y − 2q + 3p)
Answer:
−6x − 15y − 14q − 21p
Step-by-step explanation:
Let's simplify step-by-step.
−3(2x+5y)−7(2q+3p)
Distribute:
=(−3)(2x)+(−3)(5y)+(−7)(2q)+(−7)(3p)
=−6x+−15y+−14q+−21p
Answer:
=−21p−14q−6x−15y
The equation −3(2x + 5y) − 7(2q + 3p) is equivalent to −6x − 15y − 14q − 21p.Option A is correct.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that,
−3(2x + 5y) − 7(2q + 3p)
For solving the equation we have to apply the arithmetic operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
First, open the bracket and multiply,
=−3(2x + 5y) − 7(2q + 3p)
=(−3)(2x)+(−3)(5y)+(−7)(2q)+(−7)(3p)
=−6x+−15y+−14q+−21p
Rearrange the equation as
=−21p−14q−6x−15y
Thus, the equation −3(2x + 5y) − 7(2q + 3p) is equivalent to −6x − 15y − 14q − 21p.Option A is correct.

Name times when the hands of a clock form
an acute angle, a right angle, and an obtuse
angle.
Answer:
Right angle- 3:00
Acute- 1:00
Obtuse- 5:00
Step-by-step explanation:
Right angle is 90 degrees, acute is under 90 degrees but greater than zero, and obtuse is greater than 90 degrees but less than 180.
The clock hands form an acute angle between 12:00 and 1:00, right angle at 3:00, 6:00, and 9:00 and form an obtuse angle between 1:00 and 2:00, 2:00 and 3:00, 4:00 and 5:00, 5:00 and 6:00, 7:00 and 8:00, 8:00 and 9:00, 10:00 and 11:00, and 11:00 and 12:00.
When the hands of a clock move, they form different angles between them at different times.
1. Acute Angle:
An acute angle is an angle less than 90 degrees. The clock hands form an acute angle between 12:00 and 1:00.
2. Right Angle:
A right angle is exactly 90 degrees. The clock hands form a right angle at 3:00, 6:00, and 9:00.
3. Obtuse Angle:
An obtuse angle is an angle greater than 90 degrees but less than 180 degrees.
The clock hands form an obtuse angle between 1:00 and 2:00, 2:00 and 3:00, 4:00 and 5:00, 5:00 and 6:00, 7:00 and 8:00, 8:00 and 9:00, 10:00 and 11:00, and 11:00 and 12:00.

Answer:

Step-by-step explanation:
Let's solve your equation step-by-step.
3/a(−2)−4=20
−4a−6/a=20
Step 1: Multiply both sides by a.
−4a−6=20a
−4a−6−20a=20a−20a(Subtract 20a from both sides)
−24a−6=0
−24a−6+6=0+6(Add 6 to both sides)
−24a=6
−24a/−24=6/−24

9514 1404 393
Answer:
92 pounds 1 minute 15 seconds 187.5 $205.50 160 poundsExplanation:
1. The tension is proportional to distance, so twice the distance will result in twice the tension:
2 × 46 lbs = 92 lbs
__
2. The fill time is proportional to the volume, so 5/8 of the volume will take 5/8 of the time:
(5/8)(2 min) = 10/8 min = 5/4 min = 1 minute 15 seconds
__
3. When the current increases by a factor of 5/2, the power increases by the square of that factor.
(5/2)^2 × 30 = 187.5 . . . power at increased current
__
4. Working 42/28 times as many hours will result in 48/28 times as much pay:
(42/28) × $137 = $205.50
__
5. The new distance is 5000/4000 = 5/4 times the reference distance, so the new weight will be 1/(5/4)^2 = (4/5)^2 = 16/25 times the reference weight.

The coordinates of the circumcenter of the triangle are (5.5, -5.5).
The vertices of the triangle are A(3, -6), B(5, -3), and C(8, -6).The circumcenter is the point at which the perpendicular bisectors of a triangle's sides connect and are equidistant from its three vertices.The midpoint of AB is ((3+5)/2, [-6+(-3)]/2) = (4, -4.5).The midpoint of BC is ((5+8)/2, [-3+(-6)]/2) = (6.5, -4.5).The slope of AB is (-3-(-6))/(5-3) = 3/2.The slope of the perpendicular bisector of AB is -1/(3/2) = -2/3.The equation of the perpendicular bisector of AB is :(y - (-4.5)) = (-2/3)(x - 4)y + 4.5 = (-2/3)(x - 4)3(y + 4.5) = (-2)(x - 4)3y + 13.5 = -2x + 83y = -2x - 5.5The slope of BC is (-6-(-3))/(8-5) = -3/3 = -1The slope of the perpendicular bisector of BC is -1/(-1) = 1The equation of the perpendicular bisector of BC is :(y - (-4.5)) = (1)(x - 6.5)y + 4.5 = x - 6.5y = x - 11We solve for the point of intersection of the perpendicular bisectors and get (5.5, -5.5).To learn more about circumcenter, visit :

If neither a nor b are equal to zero, which answer most accurately describes the product of (a + b)(a - b)?
The product of a complex conjugate is always an imaginary number.
The product of a complex conjugate is always zero.
The product of a complex conjugate is always a mix of real and imaginary numbers.
The product of a complex conjugate is always a real number.
The statement is correct. The product of a complex conjugate is always a real number.
Given, if neither a nor b are equal to zero then we have to conclude that which of the following statement accurately describes the product of (a + ib)(a - ib). So, let's proceed to solve the question accordingly.
Now, solve the product of (a + ib)(a - ib), we get
(a + ib)(a - ib) = a(a - ib)+ib(a - ib)
= a^2-iab+iab+(ib)^2
= a^2+i^2b^2
we know that, i^2 = -1, then
= a^2+i^2b^2 = a^2+b^2
⇒(a + ib)(a - ib) = a^2+b^2
∴ a^2+b^2 will always give a real number.
Therefore, option (d) is correct. The product of a complex conjugate is always a real number.

in a mid-size company, the distribution of the number of phone calls answered each day by each of the 12 receptionists is bell-shaped and has a mean of 58 and a standard deviation of 10. using the empirical rule (as presented in the book), what is the approximate percentage of daily phone calls numbering between 28 and 88? do not enter the percent symbol.
The percentage of daily phone calls numbering 28 and 88 = 99.7%
The given Standard Deviation is 10, and the mean is 58
Using the formula
z = (X -Mean) / Standard Deviation
z value corresponding to X = 28 is
z = (28 - 58)/ 10
z = -30/10
z = -3
z value corresponding to X = 88
z = (88 - 58) / 10
z = 3
According to the empirical rule
"Empirical Rule" is also called as the three sigma rule
We have to know
One Standard Deviation of the mean , covers 68% of data
Two Standard Deviation of the mean , covers 95% of data
Three Standard Deviation of the mean , covers 99.7% of data
Therefore, +/- to the third Standard Deviation covers of the items 99.7% of data.
