20(n - 1)
Step-by-step explanation:2(n - 7) - 3(2 -6n) =
= 2n - 14 - 6 + 18n
= 20n - 20
= 20(n - 1)
The value of the equation A = 2(n - 7) - 3(2 -6n) is
A = 20 ( n- 1 )
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be A
Now , the equation A = 2( n - 7 ) - 3( 2 - 6n )
The equation can be simplified as
A = 2(n) - 2(7) - 3(2) + 3(6n)
A = 2n - 14 - 6 + 18n
Now , on adding the similar terms in the equation , we get
A = 2n + 18n - ( 14 + 6 )
A = 20n - 20
Taking the common term of 20 , we get
A = 20 ( n - 1 )
Therefore , the value of A is 20 ( n - 1 )
Hence , The value of the equation A = 2(n - 7) - 3(2 -6n) is A = 20 ( n- 1 )

At 5:00 a.m., the temperature outside was 1°F below zero. By noon, it rose by 12°F. At 7:00 p.m., the temperature dropped by 6°F. What was the evening temperature?
Answer:
5 Fahrenheit
Step-by-step explanation:
In the morning, it was 1 below zero. Subtract.
0 - 1 = -1.
Then, it went up 12 degrees.
-1 + 12 = -11.
In the evening, it went down -6.
11 - 6 = 5.

Find the general solution of the following equation: y'(t) = 3y -5
Answer:
The general solution of the equation is y = [tex]\frac{A}{3}e^{3t}[/tex] + 5
Step-by-step explanation:
Since the differential equation is given as y'(t) = 3y -5
The differential equation is re-written as
dy/dt = 3y - 5
separating the variables, we have
dy/(3y - 5) = dt
dy/(3y - 5) = dt
integrating both sides, we have
∫dy/(3y - 5) = ∫dt
∫3dy/[3(3y - 5)] = ∫dt
(1/3)∫3dy/(3y - 5) = ∫dt
(1/3)㏑(3y - 5) = t + C
㏑(3y - 5) = 3t + 3C
taking exponents of both sides, we have
exp[㏑(3y - 5)] = exp(3t + 3C)
3y - 5 = [tex]e^{3t}e^{3C}[/tex]
3y - 5 = [tex]Ae^{3t}[/tex] [tex]A = e^{3C}[/tex]
3y = [tex]Ae^{3t}[/tex] + 5
dividing through by 3, we have
y = [tex]\frac{A}{3}e^{3t}[/tex] + 5
So, the general solution of the equation is y = [tex]\frac{A}{3}e^{3t}[/tex] + 5

What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
Your car can drive 300 miles on a tank of 15 gallons
300 miles → 15 gallons
Let x be the number of miles or distance a car travel in 40 gallons
x → 40 gallons
300/x = 15/40
x = (300×40)/15
x = 800 miles
Thus, the car travels 800 miles in 40 gallons if the car can drive 300 miles on a tank of 15 gallons.

The number of possible arrangements of pictures she can hang on her wall is 120.
How many possible arrangements of pictures can she hang?
The number of possible arrangements can be determined by dividing the factorial of 6 by the factorial of 3.
Number of possible arrangements = 6! / 3!

PLEASE HELP!! ASAP NOWWWW Two races that a student runs every year are the 1492-mile race in his hometown and the -meter race in his college town. Complete parts (a) through (d) below.
Answer:
College town race is 31% of the home town race.
Step-by-step explanation:
Length of hometown race = 3 miles
Length of college town race = 1492 meters
Since 1 meter = 0.0006214 miles
Therefore, 1492 = 0.93 miles
Percentage of college town race to the hometown race,
= [tex]\frac{\text{College town race}}{\text{Home town race}}\times 100[/tex]
= [tex]\frac{0.93}{3}\times 100[/tex]
= 31%
Therefore, the college town race is 31% of the home town race.

Write an equation in slope-intercept form for the line described. Slope 9/2, passes through (0,-13/2)
Use slope-intercept equation form: [tex]y=mx+b[/tex]
We know that the slope is 9/2
[tex]y=\frac{9}{2}[/tex]
[tex]y=\frac{9}{2}x+b[/tex]
To solve for b, we can plug in the point given, since it's on the line.
[tex]-\frac{13}{2}=\frac{9}{2}(0)+b[/tex]
[tex]b=-\frac{13}{2}[/tex]

Given the graph, find the distance of GH. Round to the nearest tenth.
Answer:
GH = 6.3 units
Step-by-step explanation:
Assuming that 1 box represents 1 unit, the coordinate pair of G = (-2, -3), while H = (0, 3).
Distance between G and H = [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] G(-2, -3) = (x_1, y_1) [/tex]
[tex] H(0, 3) = (x_2, y_2) [/tex]
[tex] GH = \sqrt{(0 - (-2))^2 + (3 - (-3))^2} [/tex]
[tex] GH = \sqrt{(2)^2 + (6)^2} [/tex]
[tex] GH = \sqrt{4 + 36} = \sqrt{40} [/tex]
[tex] GH = 6.3 units [/tex] (nearest tenth)

11(15g-13)=-6 help please
Answer:
g = 0.83
Step-by-step explanation:
11(15g-13) =-6
165g - 143 = -6
165g = 137
165 165
g = 0.83
The solution of the given equation 11(15g-13) = -6 is g = 0.83
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now the given equation is,
11(15g-13) = -6
To solve the above equation following steps are taken,
Divide both the side of the equation by 11
11(15g-13)/11 = -6/11
Solving them we get,
15g - 13 = -6/11
Adding 13 both the sides,
15g - 13 + 13 = -6/11 + 13
So we obtain,
15g = -6/11 + 13
Solving the numbers right hand side,we get
15g = 137/11
Dividing both the sides by 15 we get,
g = 137/165
or, g = 0.83
Hence,The solution of the given equation 11(15g-13) = -6 is g = 0.83
