Answer:
2(n+3)-6
n=0
Step-by-step explanation:
2(3+n)-6=
Simplifying
2(3 + n) + -6 = 0
(3 * 2 + n * 2) + -6 = 0
(6 + 2n) + -6 = 0
Reorder the terms:
6 + -6 + 2n = 0
Combine like terms: 6 + -6 = 0
0 + 2n = 0
2n = 0
Solving
2n = 0
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Divide each side by '2'.
n = 0
Simplifying
n = 0

If the nth term of a sequence is
on what is the 12th term?
If the nth term of a sequence is 28-3n what is the 7th term?
Answer:
7
Step-by-step explanation:
The nth term is supposed to help us find the value of any number in the sequence. All we have to do is substitute n for 7, in this case
So, this is the general term.
= 28 - 3n
Now, to find the 7th term, we simply replace "n" with "7"
= 28 - 3(7)
Since "n" was being multiplied with 3, 7 is also going to be multiplied with 3.
= 23 - 21

A 3-gallon container of window cleaner costs $15.84. What is the price per quart?
*Hint: 1 gallon = 4 quarts*
HURRY DUE SOON PLEASE AND THANK YOU :)
Answer:
1.32
Step-by-step explanation:
3 gallon = 1
12 quarts = 4
12 quarts =1
$15.84= 1.32
Answer:
$1.32 per quart
Step-by-step explanation:
To find the price per quart, we must divide the price by the number of quarts.
price / quarts
We are told that a 3 gallon container costs $15.84. First, we must find out how many quarts are in 3 gallons.
We know that 1 gallon is equal to 4 quarts.
Let’s set up a proportion.
quarts/ gallons = quarts/ gallons
4 quarts /1 gallon = x quarts/ 3 gallons
4/1= x/3
Multiply both sides by 3
3*4/1= x/3*3
3*4/1=x
3*4=x
12=x
There are 12 quarts in 3 gallons.
Now we know how many quarts are in 3 gallons. We can find the price per quart.
price / quarts
It costs $15.84 for 12 quarts.
$15.84/12 quarts
Divide 15.84 by 12
$1.32 / quart
It costs $1.32 per quart of window cleaner.

Choose each number that shows 1/2 % as an equivalent fraction, decimal, or percent. Select all that apply.
A. 0.05
B. 2%
C. 51,000
D. 5100
E. 0.005
Answer:
E
Step-by-step explanation:
1/2% is .5% = .5/100 = .005
The required requried equivalent fraction of the given percentage value is 0.005 Option E is correct.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Given percentage term = 1/2%
Since 1/2 = 0.5, and percent % = 1/100th
Togetherly,
= 0.5/100 = 0.005
Thus, the required requried equivalent fraction of the given percentage value is 0.005 Option E is correct.

Answer:
x = 0, x = [tex]\frac{10}{7}[/tex]
Step-by-step explanation:
Given
7x² = 10x ( subtract 10x from both sides )
7x² - 10x = 0 ← factor out x from each term
x(7x - 10) = 0
Equate each factor to zero and solve for x
x = 0
7x - 10 = 0 ⇒ 7x = 10 ⇒ x = [tex]\frac{10}{7}[/tex]
Answer:
x = 1.4
Step-by-step explanation:
1. Simplify the left side so you get 14 = 10x
2. Divide the whole equation by 10
3. x = 1.4

Answer:
(3.) x = 45
Step-by-step explanation:
Because the lines are parallel and cut by the same line, the angles within are equal as well.
Which means that...

2x = x + 45
-x -x (subtract x from both sides to get rid of the single positive x)
x = 45

What is the probability that out of 175 chicks hatched on Peeper Farm, at
least 80 will be female? Assume that males and females are equally probable,
and round your answer to the nearest tenth of a percent.
A. 88.7%
B. 38.1%
C. 3.5%
D. 99.7%
The required probability of the chicks hatched on peeper is 0.45% none of the options is correct.
Given that,
Total number of hatched chicks = 175
At least 80 are female,
Probability can be defined as the ratio of favorable outcomes to the total number of events.
What is the Ratio?The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Since in the question
total chicks(total sample) = 175
probability for at least 80 chicks will be female.
Probability = number of female chicks / total number of chiks
= 80 /175
= 0.45 or 45%
Thus, The required probability of the chicks hatched on peeper is 0.45% none of the options is correct.

Help geometry what I m jlf
Picture provided
Answer:
[tex]\angle\,JLF = 114^o[/tex] which agrees with option"B" of the possible answers listed
Step-by-step explanation:
Notice that in order to solve this problem (find angle JLF) , we need to find the value of the angle defined by JLG and subtract it from [tex]180^o[/tex], since they are supplementary angles. So we focus on such, and start by drawing the radii that connects the center of the circle (point "O") to points G and H, in order to observe the central angles that are given to us as [tex]90^o[/tex] and [tex]138^o[/tex]. (see attached image)
We put our efforts into solving the right angle triangle denoted with green borders.
Notice as well, that the triangle JOH that is formed with the two radii and the segment that joins point J to point G, is an isosceles triangle, and therefore the two angles opposite to these equal radius sides, must be equal. We see that angle JOH can be calculated by : [tex]360^o-90^o-138^o=132^o[/tex]
Therefore, the two equal acute angles in the triangle JOH should add to:
[tex]180^o-132^o=48^o[/tex] resulting then in each small acute angle of measure [tex]24^o[/tex].
Now referring to the green sided right angle triangle we can find find angle JLG, using: [tex]180^o-24^o-90^o=66^o[/tex]
Finally, the requested measure of angle JLF is obtained via: [tex]180^o-66^o=114^o[/tex]
Find the value of x.
Answer:
x=root 70
Step-by-step explanation:
We have three triangles in this picture. The big triangle and 2 small triangles. They are all similar triangles.
Thus, because they are similar we have (7+3)/x=x/7
That gives us 10/x=x/7.
Cross products gives us x^2=70, so x=root 70

Which interval notation accurately represents the domain?
(–∞, 7) U (7, ∞)
(–∞, 5) U (5, ∞)
(–∞, 0) U (0, ∞)
(–∞, 10) U (10, ∞)
The domain represents interval notation is (–∞, 7) U (7, ∞) which is the correct answer would be an option (A)
What are the domain and range of the function?The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.
For all other x-values, the graph appears to be defined. Thus, with the exception of x = 7, all real numbers should fall under the function's domain. This is what that would look like in interval notation:
It is possible to write the interval (–∞, ∞). as the set of all real numbers. Keep in mind that infinity∞ or -∞ is not a real number. Both ends are shown to be excluded from the interval by the rounded brackets.
All real numbers less than but not equal to 7 are contained in the set (-∞,7). (both ends are excluded.) The collection of every real number greater than but not equal to is.
All real numbers less than and higher than are combined to form the set of all real numbers that are not equal to 7. The union operator joins two intervals together.
Hence, the domain represents interval notation is (–∞, 7) U (7, ∞)

Answer:

Step-by-step explanation:
This problem is asking specifically to prove triangles congruent using HL.
HL is a method of proving triangles congruent. HL stands for Hypotenuse-Leg. If you can show that the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg, respectively, of another triangle, then the triangles are congruent.
Looking at triangle ABC and EDC, we see that the legs AB and ED are congruent. We already have a pair of corresponding congruent legs. Now we need a pair of hypotenuses.
You need AC congruent to EC.
