how do you solve 2 - 2n = 3n + 17
Final Answer: [tex]n = -3[/tex]
Steps/Reasons/Explanation:
Question: How do you solve [tex]2 - 2n = 3n + 17[/tex]?
Step 1: Subtract [tex]2[/tex] from both sides.
[tex]-2n = 3n + 17 - 2[/tex]
Step 2: Simplify [tex]3n + 17 - 2[/tex] to [tex]3n + 15[/tex].
[tex]-2n = 3n + 15[/tex]
Step 3: Subtract [tex]3n[/tex] from both sides.
[tex]-2n - 3n = 15[/tex]
Step 4: Simplify [tex]-2n - 3n[/tex] to [tex]-5n[/tex].
[tex]-5n = 15[/tex]
Step 5: Divide both sides by [tex]-5[/tex].
[tex]n = -\frac{15}{5}[/tex]
Step 6: Simplify [tex]-\frac{15}{5}[/tex] to [tex]-3[/tex].
[tex]n = -3[/tex]

The sum of two numbers is 15. Twice one number equals 3 times the other. Find the numbers
Answer:
6 and 9
Step-by-step explanation:
x + y =15
2x = 3y Set up system of equations
x = [tex]\frac{3y}{2}[/tex] Solve for x
[tex]\frac{3y}{2}[/tex] + y = 15 Substitute
3y + 2y = 30
y = 6
x = 9
What is the equation in slope-intercept form of the line that crosses the x-axis at 12 and is perpendicular to the line represented by y = 6/5x + 9 ?
Answer:
The equation of the line in slope-intercept form is;
y = 10 - 5/6·x
Step-by-step explanation:
The given equation of the line to which the required line is perpendicular is presented as follows;
y = 6/5·x + 9
A point on the desired line = (12, 0)
The relationship of the slope, m₁ of a line, perpendicular to the another line of slope m₂, is given as follows;
m₁ = -1/m₂
Therefore;
The slope of the desired line = -1/(The slope of the given line)
The slope of the desired line = -1/(6/5) = -5/6
The equation of the desired line in point and slope form is given as follows;
y - 0 = -5/6 × (x - 12)
Therefore, the equation of the line in slope-intercept form is;
y = -5/6·x + 10 = 10 - 5/6·x.

Find x:
[tex]S=\frac{1}{sin2x}+\frac{1}{sin4x}+\frac{1}{sin8x}+...+\frac{1}{sin2^{n}x }[/tex]
Answer:
cotx - cot2ⁿxStep-by-step explanation:
Note: finding the sum not xFirst rewrite the first term as:
1/sin2x = sinx / (sinxsin2x) = sin(2x-x) / (sinxsin2x) =(sin2xcosx - cosxsinx) / (sinxsin2x) = (sin2xcosx)/(sinxsin2x) - (cos2xsinx)/(sinxsin2x) = cosx/sinx - cos2x/sin2x = cotx - cot2xNow the sum is:
S = cotx - cot2x + cot2x - cot4x +... + cot2ⁿ⁻²x - cot2ⁿx =cotx - cot2ⁿxPuteti sa ma ajutati va rog? Vreau solutii cu explicatie elaborata, nu doar raspunsul. Multumesc.

A cheetah's speed was timed overa
100-yard distance. The cheetah was
(PLEASE HELP ME)clocked running 70 miles per hour. Which
equation shows the relationship between
the distance, y, and time, x, the cheetah
runs?
Answer:
y = 70x
Step-by-step explanation:
Note that d = rt where d is the distance, r is the rate/speed, and t is the time. Since we are given that the variable x is the time, 70mph is the speed, and the variable y is the distance, we can substitute these into d = rt, which we get y = 70x.

the perimeter of a isosceles triangle is 5(2+root2) find the area
Answer:
12.5
Step-by-step explanation:
If an isosceles right triangle as the length of the equal sides is a , then the length of the hypotenuse will be a2–√ (using pythogoras theorem.
Hence the perimeter will be a+a+a2–√=a(2+2–√)
Hence the equal sides of the triangle in question has the length of a=5
Area of the triangle = 12∗Height∗Base
=12∗5∗5=12.5
On Monday Matty worked for 450 minuites in his office on Tuesday he worked half the numbers of minute he worked on Monday on wends day he worked only 1/2 day Wichita was 300 minute how many more minutes did he work on wensday then thursday
Answer:
The answer is 75 minutes.
Explanation :
Wednesday is 300 minutes & Tuesday is 225 minutes because 450 ÷ 2 = 225.
Wednesday is 300 minutes & Tuesday is 225 minutes because 450 ÷ 2 = 225. SO 300 - 225 = 75.
CAN YOU PLS GIVE ME BRAINLIST? THANK YOU! :))
Answer:
He worked for 75 more minutes on Wednesday then on Tuesday.
Step-by-step explanation:
So since we know that Matty worked for 450 minutes in his office on Monday, we can find out for how long he was working on Tuesday since we know that.......
Let "y" be the number of minutes Matty will work on Tuesday
Let "x" be the number of minutes Matty worked on Monday
[tex]y = \frac{x}{2}[/tex]
Substitute the values we have and get......
[tex]y = \frac{450}{2}[/tex]
[tex]y = 225[/tex]
So now we can find out how much more he worked on Wednesday then on Tuesday by doing the following......
Let "w" be the number of minutes Matty worked on Wednesday, then.......
The answer = [tex]w - y[/tex]
The answer = 300 - 225
The answer = 75

Why do scientists use models?
A)
Models are unreliable.
B)
Models waste natural resources.
Models predict not just describe events.
Models are based on scientific laws and principals so they are more
reliable than the real thing.
D)

The formula C=5/9(F−32) can be used to convert temperature from Celsius (C) to Fahrenheit (F). The highest temperature ever recorded in the United States was 134 ∘F in Death Valley on July 10, 1913. What was the temperature that day in Celsius, rounded to the nearest degree?
Answer:
57 °C.
Step-by-step explanation:
The formula that is used to convert temperature from Celsius (C) to Fahrenheit (F) is given by :
[tex]C=\dfrac{5}{9}(F-32)[/tex] ...(1)
If T = 134° F, we need to convert the temperature in Celsius.
Put F = 134, in equation (1)
[tex]C=\dfrac{5}{9}(134-32)\\\\=\dfrac{5}{9}\times 102\\\\=56.66^{\circ} C\\\\\text{or}\\\\T=57^{\circ} C[/tex]
So, the temperature on that day is 57 °C.

If P(A) is ⅗. Find P (not A)
Work Shown:
P(A) + P(not A) = 1
P(not A) = 1 - P(A)
P(not A) = 1 - 3/5
P(not A) = 5/5 - 3/5
P(not A) = (5-3)/5
P(not A) = 2/5
Step-by-step explanation:
P(A) + P(not A) = 1. Since P(A) = 3/5, we have:
P(not A) = 1 - P(A) = 1 - 3/5 = 2/5.

At Charles School, 1/5 of the 75 students in seventh grade play in the jazz band. how many seventh graders play in the jazz band?
Answer:
15
Explanation
1/5x75=75/5 =15
15 seventh graders play in the jazz band as per the given ratio.
What is the ratio?One quantity can be expressed as a fraction of other quantities using a ratio, which is a number. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Given At Charles School, 1/5 of the 75 students in seventh-grade play in the jazz band.
In the form of a ratio
1/5 the students out of 75 play in the jazz band
Total students play in the jazz band = 75* 1/5
Total students play in the jazz band = 15
Therefore, The jazz band has 15 seventh graders playing according to the ratio.
