The value for the n is undefined, 3, 3/2.
In this problem, we are dealing with equations where equations are mathematical statements containing two arithmetical expressions on both sides of the sign of 'equal to (=)'. It appears the relationship of equality between the expression composed on the left side with the expression composed on the proper side. In each condition we have, (L.H.S = R.H.S), left hand side = right-hand side. Conditions can be fathomed to discover the value of an unknown variable representing an unknown amount. If there's no 'equal to' symbol within the statement, it implies it isn't a condition. It'll be considered as an expression. Equations with 1 as the degree are considered linear equations. Equations with degree 2 are quadratic equations and the last Equations with degree 3 are known as cubic equations.
So , for 0n = 6 , it undefined as the L.H.S becomes zero
for 2n=6 => n=6/2=3

use the aleks calculator to find 46% of 20 do not round
The value of the part of 20 that is 46% is 9.2.
How to determine the percentage of a number?Percentage is simply a number or ratio expressed as a fraction of 100.
It is expressed as;
Percentage = ( Part / Whole ) × 100%
Given the data in the question;
Percentage = 46%Whole = 20Part = ?Plug the given values into the above formula and solve for the part.
Percentage = ( Part / Whole ) × 100%
46% = ( Part / 20) × 100%
46/100 = ( Part / 20 ) × 100/100
46/100 = ( Part / 20 ) × 1
46/100 = Part / 20
Cross multiply
46 × 20 = Part × 100
920 = Part × 100
Part = 920/100
Part = 9.2
Therefore, 9.2 is 46 percent of 20.

Solve the system of linear equations using the substitution method.
2d + 8y = 20 and y = 2
A. (1, 1)
B. 4, 4
C. (1, 2)
D. (2, 2)
Answer:
D
Step-by-step explanation:
2d + 8y = 20
y = 2
substitute y = 2 into the other equation
2d + 8(2) = 20
2d + 16 = 20 ( subtract 16 from both sides )
2d = 4 ( divide both sides by 2 )
d = 2
solution is (2, 2 )
answer-> D. (2,2)
Given,
2d + 8y = 20 .............................................(Equation i)
y = 2 .............................................................(Equation ii)
substituting y = 2 in equation i, we get
2d + 8(2) = 20
2d + 16 = 20
2d = 20 - 16
2d = 4
d = 2
Hence the correct answer would be option D. (2,2)

in Oak Grove, Erik bought a mattress that was marked down 70% from an original price of $500. If the sales tax in Oak Grove is 8%, what was the total cost of the mattress?
The mattress has a total cost of $24.28
How to determine the total cost for the mattress?From the question, the given parameters are:
Cost of a mattress = $74.95
Markdown = 70%
Sales tax in oak grove = 8%
Using the sales tax and the markdown, the total cost for the mattress is calculated using
Total cost of mattress = Cost of a mattress * (1 + Sales tax) * (1 - Markdown )
Substitute the known values in the above equation
So, we have the following equation
Total cost of mattress = 74.95 * (1 + 8%) * (1 - 70%)
Evaluate the products
Total cost of mattress = 24.28
Hence, the total cost of the mattress is $24.28

2. Ryan is running in a 5-kilometer race. How many feet will he run in the race? Use the conversion rates 5, 280ft = 1mi and 1m i approx 1.61 km. Round to the nearest hundred feet
Answer:
16,400 ft
Step-by-step explanation:
You want to know the number of feet in a 5 km race, rounded to the nearest hundred. You are given conversion factors 5280 ft = 1 mi = 1.61 km.
Unit conversionUnit conversion can be done by multiplying by a conversion factor whose numerator is equal to its denominator, and that cancels unwanted units, replacing them with units you want.
[tex]5\text{ km}=5\text{ km}\times\dfrac{5280\text{ ft}}{1.61\text{ km}}\approx16397.5\text{ ft}\approx\boxed{16,\!400\text{ ft}}[/tex]
__
Additional comment
Both of the given conversions are equal to 1 mile, so their ratio is 1. We put feet on top of the fraction, because that is the unit we want. The km value is in the denominator so the km units in numerator and denominator cancel.
The conversion for km is 1 mi = 1.609344 km (exactly). The actual conversion to ft will give 16,404 76/381 ft. This has a very long repeating decimal fraction.

Step-by-step explanation:
1/3 = 3/15
2/5 = 6/15
1 - 3/15 - 6/15 = 6/15
6/15 = 24600
24600 ÷ 6 × 15 = 61500
Answer:
92250
Step-by-step explanation:
Forming algebraic equation and solving:
Let the income = x
Amount spent on housing = (1/3) of the income
[tex]\sf = \dfrac{1}{3}x[/tex]
Amount spent of daily expenditure = (2/5) of the income
[tex]\sf =\dfrac{2}{5}x[/tex]
Income = Savings + housing expenditure + daily expenditure
Income - housing expenditure - daily expenditure = savings
[tex]\sf x - \dfrac{1}{3}x-\dfrac{2}{5}x=24600\\\\\\\dfrac{x*15}{1*15}-\dfrac{1*5}{3*5}x-\dfrac{2*3}{5*3}x = 24600\\\\\\[/tex]
[tex]\sf \dfrac{15}{15}x-\dfrac{5}{15}x-\dfrac{6}{15}x = 24600\\\\\\\dfrac{(15 -5 - 6)}{15}x = 24600[/tex]
[tex]\sf \dfrac{4}{15}x = 24600[/tex]
[tex]\sf x = 24600 *\dfrac{15}{4}\\\\ x = 6150*15[/tex]

a couple has four children. neither the father nor the mother is bald; one of the two sons is bald, but neither of the daughters is bald. (a) if one of the daughters marries a nonbald man and they have a son, what is the chance that the son will become bald as an adult? (b) if the couple has a daughter, what is the chance that she will become bald as an adult?
If one of the daughters marries a non-bald man and they have a son, the chance that the son will become bald as an adult is 0%
If the couple has a daughter, the chance that she will become bald as an adult is 0%
In the question, we have been given that the neither the father nor the mother is bald, and out of the four children only one son is bald, but the other son and the two daughters are not bald, now we solve the following:
Part a
A chance that the son will become bald as an adult:
If the daughter has no bald gene (XX), and she marries a non bald man then there is 0% chance that the son will become bald as an adult because neither the mom nor the dad has the baldness gene
Part b
The chance that she will become bald as an adult:
If the daughter having a bald gene ([tex]X^{b} X[/tex]) marries a non bald (XY)man then also there is a 0% chance that the daughter will be bald as an adult. As the baldness is a recessive trait, for the daughter to be bald she needs to have two baldness gene( one from father and one from mother). And since this is not the case the daughter might have baldness gene but the phenotype will be non-bald.

What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The algebraic expression is,
'' An integer is subtracted from 8 times the next consecutive integer, the difference is 71.''
Now,
Let a number = x
Then, Its consecutive number = (x + 1)
So, We can formulate;
⇒ 8 (x + 1) - x = 71
Solve for x as;
⇒ 8x + 8 - x = 71
⇒ 7x + 8 = 71
⇒ 7x = 71 - 8
⇒ 7x = 63
⇒ x = 9
Thus, The value of greater number = x + 1
= 9 + 1

What is elevation?The elevation is the distance above sea level. They are usually measured in meters or feet.
Let t be the height of the tree, then the length of the shadow will be:
Shadow length = t/tan(α)
where α is the angle of elevation. The difference in shadow lengths is:

Answer:
Equation: -5 <3× -8

3 <3x
_ _
3. 3
Answer: 1 = X
Step-by-step explanation:
Equation: -5 <3× -8
First Step: You must add 8 to -8 and move it to both sides. The reason why we do this is because on the left side we have 1 number and on the right side we have 2 numbers. We see that the right side has more numbers than the left, so we must move the -8 turning it to a positive 8 (8-8 cancels each other making 0) and adding the +8 in -8 to -5 as well, since we're adding to both sides.
Second Step: Since we added 8 to -5, it equals 3 now 8-5=3. Changing the equation to 3 <3x. Now we have to divide 3 to both sides as well, because we want the x to be by itself. So, 3 ÷ 3 = 1 and 3x ÷ 3 = x
Results: After our extraordinary calculations we recieve
