-4x-2(8x+1)=-(-2x-10)
Answers
The first step is to distribute. On the left side of the equation, multiply the -2 by both terms inside the parentheses; on the right side of the equation, multiply the -1 by both terms inside the parentheses:
-4x - 2(8x + 1) = -(-2x - 10)
-4x - 16x - 2 = 2x + 10
Next, combine like terms.
-4x - 16x - 2 = 2x + 10
-20x - 2 = 2x + 10
Then subtract 2x from both sides and add 2 to both sides to get like terms together; combine like terms.
-20x - 2 = 2x + 10
-20x - 2x = 2 + 10
-22x = 12
Lastly, divide both sides by -22 and simplify.
-22x = 12
x = 12/-22
x = -6/11
Answer:
-6/11

What are permutation and combination?A permutation is an act of correctly arranging things or pieces. Combinations are a method of taking stuff or pieces from an assortment of items or sets in which the order of the items is irrelevant.
The value of the expression ¹²P₃ is given as,
¹²P₃ = 12! / (12 - 3)!
¹²P₃ = 12 x 11 x 10 x 9! / 9!
¹²P₃ = 1,320
The value of the expression ¹⁰C₄ is given as,
¹⁰C₄ = 10! / [(10 - 4)! x 4!]
¹⁰C₄ = 10 x 9 x 8 x 7 x 6! / (6! x 4 x 3 x 2 x 1)
¹⁰C₄ = 10 x 3 x 7
¹⁰C₄ = 210
The value of the expression ¹²P₃ and ¹⁰C₄ will be 1,320 and 210, respectively.

Answers
C)neither arithmetic nor geometric
EXPLANATION
The given sequence is
[tex]99,89.9,78.8,68.7,...[/tex]
Let us check to see if there is a constant difference.
[tex]89.9 - 99 = - 9.1[/tex]
[tex]78.8 - 89.9 = - 11.1[/tex]
The two difference are not the same.
Since there is no constant difference, the sequence is not arithmetic.
Let us check to see if there is a common ratio,
[tex] \frac{89.9}{99} = \frac{899}{990} [/tex]
[tex] \frac{78.8}{89.9} = \frac{788}{899} [/tex]
Since the ratio is not the same,the sequence is not geometric too.
The sequence is neither arithmetic nor geometric.

what is 6.7086 rounded to the nearest tenth
Answers
Decimals used to confuse me a lot! :D
When a question asks to round the decimal to the "nearest tenth", it simply means to round it to one decimal place.
6.7086 would be rounded to 6.7 if we round it to the nearest tenth. See, the 7 is in one place after the decimal point.
The best way to understand decimal places, in my opinion, is to search up a tenths, hundredths, thousandths, etc. chart. Hope this gave you a better understanding of decimal places!

Prove that (n+1)^2 - (n-1)^2 is always odd for all positive integer values of n.
Answers
Do you know how to expand a binomial squared? If you do here's one way to do it.
(n +1)^2 = n^2 + 2n + 1
(n - 1)^2 = n^2 - 2n + 1
Now put them together
(n^2 + 2n +1) - (n^2 - 2n + 1) Remove the brackets.
(n^2 + 2n + 1 - n^2 + 2n - 1
2n + 2n = 4n is what is left. What you have given us is always even.
To show (but not to prove) that the result is even, let n = 10
(10 +1)^2 - (10 -1 )^2
(11)^2 - (9^2)
121 - 81 = 40
Maybe if you start out with (say) n = 7 (an odd number) you might get an odd number.
(7 + 1)^2 - (7 - 1)^2
8^2 - 6^2 (doesn't matter what the answer is. It will be even.
64 - 36 = 28 and that is also even.
Nice question. Maybe because you are in middle school mathematics, this last proof is good enough. In any case, you will never get an odd result. Isn't that something? Thanks for posting.

A CD usually sells for $14 if the CD is 30% off and still taxes 8% what is the total price of the CD including tax
Answers
The 0.004 will likely round up to $10.59
30% of price = 30% * $14 = 0.30 * $14 = $4.20
Sale price: $14 - $4.20 = $9.80
Tax on $9.80: 8% of $9.80 = 0.08 * $9.80 = $0.784 round to $0.78.
Add tax to sale price: $9.80 + $0.78 = $10.58
Answer: The final price is $10.58

Tamara need tiles to make a border for her bathroom wall.The border will be 9 feet long and 1/3 foot wide.Each tile measures 1/3 foot by 1/3 foot.Each box of tiles contains 6 tiles.How many boxes of tiles doe Tamara need?Write two equations that can be used to solve the problem.
Answers
Answer:
e
Step-by-step explanation:
Final answer:
Tamara needs 5 boxes of tiles to complete her bathroom wall border. The calculations involve finding the total area of the border, the area covered by one tile, and then determining the total number of tiles and boxes required.
Explanation:
To determine how many boxes of tiles Tamara needs for her bathroom wall border, we first calculate the total area of the border and then divide that by the area of an individual tile. The area of the border is obtained by multiplying its length by its width. Then, knowing that each box contains 6 tiles, we calculate how many boxes she needs.
The area needed = Length of border × Width of border = 9 feet × \(1/3\) foot.Each tile covers an area = \(1/3\) foot × \(1/3\) foot.Therefore, the number of tiles needed = Total area needed / Area covered by one tile.Finally, the number of boxes needed = Number of tiles needed / 6 (since each box contains 6 tiles).First Equation
Area of border = 9 × \(1/3\) = 3 square feet.
Second Equation
Number of tiles = 3 / (\(1/3\) × \(1/3\)) = 3 / \(1/9\) = 27 tiles.
Therefore, the number of boxes needed = 27 / 6 = 4.5.
Since Tamara cannot purchase half a box, she would need to round up to 5 boxes in total to complete the border.
marcela made 4 out of 16 free throws. write the fraction of free throws she made in simplest form
Answers
Answer:
1/4
Step-by-step explanation:
Final answer:
The fraction of free throws Marcela made in simplest form is 1/4.
Explanation:
Marcela made 4 out of 16 free throws. To express this fraction in simplest form, we divide both the numerator (the top number) and the denominator (the bottom number) by their greatest common divisor. In this case, the greatest common divisor of 4 and 16 is 4.
To simplify the fraction:
Divide the numerator (4) by 4, which equals 1.Divide the denominator (16) by 4, which equals 4.Therefore, the fraction of free throws Marcela made in simplest form is 1/4.

Sarah has 1 1/5 cups of nuts and must add 2/5 cup of dried fruit to make a total of 1 3/5 cups of trail mix.
Explanation:
Imagine Sarah is making a trail mix for a hiking trip. She already has 1 1/5 cups of nuts and wants to add more dried fruit to reach a total of 1 3/5 cups of trail mix. To find out how much dried fruit she should add, we can set up the equation:
1 1/5 + x = 1 3/5
Converting mixed numbers to improper fractions gives us:
6/5 + x = 8/5
Subtracting 6/5 from both sides, we find that x (the amount of dried fruit to be added) is:
x = 8/5 - 6/5
x = 2/5
Therefore, Sarah needs to add 2/5 cup of dried fruit to the nuts to make 1 3/5 cups of trail mix.
the solution for which of the following requires use of absolute value?
a: At a school fundraiser, students washed twenty cars for 5$ per vehicle. Each driver donated and additional $3-$5. How much money was raised.
b: A local merchant donates 10% of her sales on the first day of each month to a local cause. if her annual donations total $1500 what is her average daily sales?
c: If gas cost $3.50 per gallon, how much did Celia pay to fill her tank with 8.2 gallons?
d: Marissa ran a half marathon (about 13.1 miles) in 2 hours and 4 minutes. what was her speed?
Answers
we know that
raised money=total vehicle*[$5+absolute value($3-$5)]
raised money=20*[$5+absolute value(-2)]
raised money=20*[$7]
raised money=$140
the answer Part a) is $140
Part b)A local merchant donates 10% of her sales on the first day of each month to a local cause. if her annual donations total $1500 what is her average daily sales?
step 1
divide $1500 by 12
1500/12=$125/month
if $125 is ------------> 10%
x------------------> 100%
x=100*125/10-----> x=$1250
the answer Part b) is $1250
Part c)If gas cost $3.50 per gallon, how much did Celia pay to fill her tank with 8.2 gallons?
multiply $3.50 by 8.2 gallons
3.5*8.2=$28.7
the answer Part c) is $28.7
Part d) Marissa ran a half marathon (about 13.1 miles) in 2 hours and 4 minutes. what was her speed?
we know that
speed=distance /time
distance=13.1 miles
time=2 hours and 4 minutes----> 2+(4/60)---> 2.07 hour
time=2 hours and 4 minutes----> 2*60+(4)---> 124 minutes
speed=13.1/2.07----> 6.33 miles/hour
speed=13.1/124----> 0.106 miles/minutes
the answer part d) is 6.33 miles/hour or 0.106 miles/minutes
The solution to problem a) requires the use of absolute value
a). Minimum =$160
Maximum =$200
b). $410.96
c). $28.7
d). 0.105645161 miles per minute.
Explanation a.
For the first statements (a) there would be no absolute value. It is a range.
There are 20 vehicles, each washed at $5.
$5×20=$100
If there are 20 vehicles then there are 20 drivers.
$3×20=$60 or $5×20=#100
Total amount of money raised
(60+100) to (100+100)
Minimum =$160
Maximum =$200
Explanation b
Let x be her daily sales. There are 365 days in one year.
Donation for one day = 10% of x = 0.01x
Donation for 1 year =0.01x×365=3.65x
3.65x=1500
x=410.96
Donation for 1 day = $410.96
Explanation c.
Cost of 1 gallon = $3.50
Cost of 8.2 gallon = $3.50×8.2=$28.7
Explanation d.
Marissa runs 13.1 miles in 2 hours and 4 minutes
That is to say that she runs 13.1 miles in ((2×60)+4) minutes.
((2×60)+4)=124 minutes.
speed=distance/(time taken)
speed=13.1/124=0.105645161 miles per minute.
