Answer:
n=1
Step-by-step explanation:
(5 + 4n) + 11 = -5 (3 - 7n)
5+4n+11=−5(3−7n)
simplify
4n+16=−5(3−7n)
expand
4n+16=−15+35n
regroup
4n+16=35n−15
subtract
16=35n−15−4n
simplify
16=31n−15
add
16+15=31n
simplify
31=31n
n=1
Hope this helps :)
(pls mark brainliest)
Answer:
n=22
Step-by-step explanation:
8 (5 + 4n) + 11 = -5 (3 - 7n)
distribute
=> 40+32n+11=-15+45n
add like terms
=> 51+32n=-15+35n
subtract 35n on both sides and subtract 51 on both sides
32n-35n=-15-51
add like terms
-3n=-66
divide both sides by -3
n=22

Answer:
Part A: 4 3/4
Part B: 1 1/4
Step-by-step explanation:
A: sum of 2 1/2 and 2 1/4 = 2 2/4 + 2 1/4 = 4 3/4
B: 6 can be made to be 5 4/4 because it is 5 + 1
5 4/4 - 4 3/4 = 1 1/4
Can someone help with this.
The sum of two numbers is 25. Twice the first number minus the second is 6. Find the numbers.
Answer:
Step-by-step explanation:
x + y = 25
2x - y = 6 Solve for y in this the second equation. Add y to both sides
2x = 6 + y The ys on the left cancel. Subtract 6 from both sides.
2x - 6 = y
Put this value of y into the first equation
x + y = 25
x + 2x - 6 = 25 Combine on the left
3x - 6 = 25 Add 6 to both sides.
3x = 25 + 6 Combine the right
3x = 31 Divide by 3
x = 31 / 3
x = 10.333333
x + y = 25
10.33333 + y = 25 Subtract 10.33333
y = 25 - 10.333333
y = 14.666666
x + y = 25
10.33333 + 14.66666
25 approximately.
2x - y = 6
2*10.33333 - 14.66666
20.66666 - 14.66666
6
You should note that those numbers are repeating decimals
2x - 6 = y

On a scale drawing, 1 centimeter represents 2 meters. What length on the drawing should be used to represent 3.2 meters?
Answer:
The answer to this problem is 36
Answer:
Your answer will be 1.6cm
Step-by-step explanation:
1cm represents => 2m
Or
2m is represented by 1 cm
then,
1m will be represented by => 1/2 cm [{unitary method}]
then,
3.2 m will be represented by
=> (1/2 × 3.2) cm [{unitary method}]
=> ( 3.2 / 2) cm
=> 1.6 cm
Therefore| : Ans will be 1.6 cm
A website averages 800 visitors per day.Based on that rate,what percent of a weeks visitor come to the website on an average day?Round your answer to the nearest tenth.
Answer:
[tex]14.2857[/tex] % of a weeks visitor come to the website on an average day
Step-by-step explanation:
Visitors on the website per day [tex]= 800[/tex]
Visitor on the website in seven day [tex]= 800*7[/tex]
Percent of visitor on any average to the total visitors in a week
[tex]= \frac{800}{800*7} *100\\= \frac{100}{7}\\= 14.2857[/tex]

Find the 77th term for each sequence(use the equation: an=a1+(n-1)d)
A)5,10,15,20,25...
B)17,14,11,8,5
Step-by-step explanation:
[tex]an = a1 + (n - 1)d \\ d = a2 - a1 \\ a1 = 5 \\ a2 = 10 \\ d = 5 \\ an = 5 + (n - 1)5 \\ an = 5n \\ a77 = 5 \times 77 = 385[/tex]
For B
[tex]a1 = 17 \\ a2 = 14 \\ d = 14 - 17 = - 3 \\ an = 17 + (n - 1) \times - 3 \\ an = 17 - 3n + 3 \\ an = 20 - 3n \\ a77 = 20 - 3 \times 77 \\ a77 = - 211[/tex]

LIFE
I wonder what it's all about, and why
We suffer so, when little things go wrong?
We make our life a struggle,
When life should be a song.
Our troubles break and drench us,
Like spray on the cleaving prow
Of some trim Gloucester schooner.
As it dips in a graceful bow.
Our troubles break and drench us
But like that cleaving prow,
The wind will fan and drys us.
And we'll watch come other bow.
But why does sorrow drench us
When our fellow passes on?
We just exchanged life's dreary dirge
For an eternal life of song.
What is the inborn human trait
That frowns on a life of song?
That makes us weep at the journey's end,
When the journey was oft-times wrong?
Weep when we reach the door
That opens to let us in,
And brings to us eternal peace.
As it closes again in sin.
Millions have gone before us,
And millions will come behind.
So why do we fight
At a fate both wise and kind.
We hang into a jaded life
A life full of sorrow and pain.
A life that warps and breaks us,
And we try to run through it again and again.
