1/2 (n – 4) – 7 = -2n+6
Answers
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

If m/8 =57, find m/1.
Answers
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.

Given: 5, 9, 13, 17
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.
Answers
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

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?
Answers
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

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
Answers
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].

BC=26
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:
[tex]BC=26[/tex]

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,

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
