1/2 (n – 4) – 7 = -2n+6
Answer:
n = 6
Step-by-step explanation:
Simplify [tex]\frac{1}{2}[/tex] · [tex](n-4)-7[/tex]
n/2 -2 -7 =-2n +6
n/2 - 9+ -2n +6
Move all terms containing n to the left side of the equation.
n/2 - 9 +2n =6
To write 2
n as a fraction with a common denominator, multiply by
n/2 + 2n *(2/2) -9 = 6
combine 2n and (2/2)
n/2 + (2n*2)/2 -9 = 6
Combine the numerators over the common denominator.
(n+2n*2)/2 - 9 = 6
Simplify each term.
(n(1+2*2))/2 - 9 = 6
(n(1+4))/2 -9 = 6
(n*5)/ 2 - 9 = 6
5n/2 - 9 =6
Move all terms not containing n to the right side of the equation.
Add 9 to both sides of the equation.
5n/2 = 6 + 9
5n/2 = 15
Multiply both sides of the equation by 2/5
2/5 * 5n/2 = 2/5 *15
Simplify both sides of the equation.
2/5 * 5n/2
Cancel the common factor of 2
Cancel the common factor of 5
n = 2/5 *15
Cancel the common factor of 5
n = 2 * 3
Multiply
n = 6

can someone please help!!
Answer:
10
Step-by-step explanation:
You would plug in -4 for p which would be -4 squared so you would do -4 time -4 which is positive 16.Then you would plug in 6 for n so you equation would turn into 16-6= which equals you answer of 10.
Rewrite in simplest terms: -7(-7d – 6) – 4d

Step-by-step explanation:
Suppose the equation for line a is given by 2x-5y=15. If line a and b are parallel and the point (-10, 3) lies on line b, then write the equation in slope intercept form for line b
Answer:
Line [tex]b[/tex] is represented by the equation [tex]y = \frac{2}{5}\cdot x + 7[/tex].
Step-by-step explanation:
Let be line [tex]a[/tex] represented by [tex]2\cdot x - 5\cdot y = 15[/tex], whose explicitive form is:
[tex]5\cdot y = 2\cdot x - 15[/tex]
[tex]y = \frac{2}{5}\cdot x - 3[/tex]
As line [tex]b[/tex] is parallel to line [tex]a[/tex], its slope is equal to [tex]\frac{2}{5}[/tex]. Two lines that are parallel to each other have the same slope but different y-intercept. In addition, we know that point (-10, 3) lies on that line and we must find the y-intercept ([tex]k[/tex]):
[tex]y = \frac{2}{5}\cdot x +k[/tex]
If [tex]x = -10[/tex] and [tex]y = 3[/tex], then:
[tex]3 = \frac{2}{5}\cdot (-10)+k[/tex]
[tex]k = 3+\frac{2}{5} \cdot (10)[/tex]
[tex]k = 7[/tex]
Line [tex]b[/tex] is represented by the equation [tex]y = \frac{2}{5}\cdot x + 7[/tex].
If m/8 =57, find m/1.
Answer:
696
Step-by-step explanation:
[tex]\frac{m}{8} = 87[/tex]
First I would multiply each side by 8 to find what M is (because if you multiple m/8 by 8 the 8s will cancel out).
[tex]m=87*8\\m = 696[/tex]
Because any number divided by 1 would just be itself, 696/1 is just 696.
Answer: m/1= 7.125 or 7.1 (rounded)
Step-by-step explanation:
if m/8=57 then m/1 multiplied by 8 would be 57 . so you do the opposite and divide 57 by 8.

How much total money would Zoey have to pay in a month in which she downloaded 45 songs? How much would she have to pay if she downloaded ss songs?

What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Zoey signed up for a streaming music service that costs $7 per month. The service allows Zoey to listen to unlimited music, but if she wants to download songs for offline listening, the service charges $0.75 per song.
Let x be the number of songs and y be the total amount. Then the equation will be
y = 0.75x + 7
The total money would Zoey have to pay in a month in which she downloaded 45 songs will be
y = 0.75 × 45 + 7
y = 33.75 + 7

1. What is the common difference, d, of the sequence.
2. Write the formula needed to get the general term.
3. Find the 25th term.
Step-by-step explanation:
1).To find the common difference of the sequence subtract the previous term from the next term
That's
d = 9 - 5 = 4 or
d = 13 - 9 = 4 or
d = 17 - 13 = 4
Since it's the same for any of the terms chosen
The common difference = 4
2).The sequence above is an arithmetic sequence
For an nth term in an arithmetic sequence
A(n) = a + ( n - 1)d
where a is the first term
n is the number of terms
d is the common difference
From the question
a = 5
d = 4
We have
A(n) = 5 + ( n - 1)4
= 5 + 4n - 4
= 4n + 5 - 4
We have the answer as
A(n) = 4n + 13).To find the 25th term substitute the value of n that's 25 into the formula
We have
A(25) = 4(25) + 1
= 100 + 1
We have the final answer as
A(25) = 101Hope this helps you

If B is the midpoint of AC, and AC=8x-20, find BC.
Answer:
[tex]BC=26[/tex]
Step-by-step explanation:
Start with:
[tex]AB+BC=AC[/tex]
Since [tex]B[/tex] is the midpoint, we also know that:
[tex]AB=BC[/tex]
Knowing this, we can use a system of equations and substitute [tex]AB[/tex] for [tex]BC[/tex] in the equation we started with:
[tex]AB+AB=AC[/tex]
Let's identify our values:
[tex]AB=3x-1\\AC=8x-20[/tex]
Substitute:
[tex]3x-1+3x-1=8x-20[/tex]
Combine like terms:
[tex]6x-2=8x-20[/tex]
Add [tex]20[/tex] to both sides of the equation:
[tex]6x+18=8x[/tex]
Subtract [tex]6x[/tex] from both sides of the equation:
[tex]18=2x[/tex]
Divide by the coefficient of [tex]x[/tex], which is [tex]2.[/tex]
[tex]x=9[/tex]
Substitute [tex]9[/tex] into [tex]3x-1[/tex]
[tex]3(9)-1[/tex]
Solve:
[tex]AB=26[/tex]
Remember that [tex]AB=BC[/tex], thus:

A jet travels 2904 miles against the wind in 4 hours and 3504 miles with the wind in the same amount of time. What is the rate of the Jet in still air and what is
the rate of the wind?
Step-by-step explanation:
2904/4 = 726 miles per hour (against wind)
3504/4 = 876 miles per hour (with wind)
Assuming the wind stayed constant, the rate of the wind would be the difference between these two values halved
876-726=150
150/2=75 miles per hour (wind speed)
Therefore the rate in still air would be the middle value of the two:
726+75=801 miles per hour

the denominators need to be the same so if we multiply the first fraction by 6 and the second by 5, our new equation is
24/30 - 5/30
24-5=19
19/30 is your answer
Answer & Step-by-step explanation:
[tex]\frac{4}{5}-\frac{1}{6}[/tex]
When you need to subtract fractions, the denominators (bottom) need to be the same. For this, you have to multiply both fractions until the bottom numbers are the same:
Find the lowest common multiple of the denominators:
[tex]5,10,15,20,25,30\\6,12,18,24,30[/tex]
The LCM of 5 and 6 is 30. Now you have to multiply the top and bottom of the fractions until you get a denominator of 30*:
[tex]\frac{4(6)}{5(6)}=\frac{24}{30}\\\\\frac{1(5)}{6(5)}=\frac{5}{30}[/tex]
So,
[tex]\frac{24}{30} -\frac{5}{30}[/tex]
When you subtract fractions, you only change the numerators (top). The denominator will stay the same:
[tex]\frac{24}{30} -\frac{5}{30}=\frac{19}{30}[/tex]
Since the fraction can't be further simplified, [tex]\frac{4}{5}-\frac{1}{6}=\frac{19}{30}[/tex]
:Done
*When you are finding the same denominators, you need to multiply a single fraction's numerator and denominator by the same number. The two different fractions don't need to be multiplied by the same number:
[tex]\frac{x(a)}{y(a)}-\frac{w(b)}{z(b)}[/tex]

Katie's car averages 35 miles per hour. She has marked her
distance traveled after 5, 6, and 7 hours. List the elements in
the range of the function that would be used to determine how
far Katie can travel.
Answer: 175, 210, 245
Step-by-step explanation:
The distance covered by the Katires car after 5, 6, and 7 hours will be 175 ,210, and 245 miles.
What are work and time?Work is the completion of any task for example if you have done your homework in 5 hours then you have done 5 hours.
Another example of work is that if you have done your food by 1 hour it means your work duration is 1 hour so work is basically the time duration of any task which you have done.
Distance = speed × time
Given,
Speed = 35 hours.
Distance covered in 5 hours ⇒
35 × 5 = 175 miles.
Distance covered in 6 hours ⇒
35 × 6 = 210 miles
Distance covered in 7 hours ⇒
35 × 7 = 245 miles.
Hence, the distance covered by the Katires car after 5, 6, and 7 hours will be 175,210, and 245 miles.

Mr. mehta is trying to subtracting one polynomial from another polynomial, what must he do first?
The first thing he has to do is take that "minus" sign through the parentheses containing the second polynomial. Some students find it helpful to put a " 1 " in front of the parentheses, to help them keep track of the minus sign. Here's what the subtraction looks like, when working horizontally.
