Nate is 2 years younger than Alan and Kai is half Alan's age. The sum of their ages is 63. How old is Kai?
The ages of Alan, Nate and Kai is 26, 24 and 13 years respectively
AlgebraAlan's age = x yearsNate's age = (x - 2) yearsKai's age = 1/2xTotal ages = 63 years63 = x + (x - 2) + 1/2x
63 = x + x - 2 + 1/2x
63 = 2 1/2x - 2
63 + 2 = 2 1/2x
65 = 5/2x
divide both sides by 5/2x = 65 ÷ 5/2
x = 65 × 2/5
= 130/5
x = 26
Recall,
Alan's age = x years

Can someone answer this for me, I’ve been trying for the past 30 minutes, thank you
Answer:
1/2
Step-by-step explanation:
When x = 20, y = 0
When x = 40, y = 10
When x = 60, y = 20
When x = 80, y = 30
When x = 100, y = 40
The slope is the change in y divided by the change in x.
First, find the change in x and y between any two points. We will use the first two points, (20, 0) and (40,10)
The change in x is 40 - 20 = 20
The change in y is 10 - 0 = 10
Divide the change in y by the change in x.
10 / 20 = 1/2
The slope is 1/2

If the loan offers no payments for the first 5 months, the amount owed by Dillion when he begins making the payments is $2,441.03
What is the effective monthly interest rate on the loan?
The effective monthly interest rate on the loan is determined as the annual percentage rate(APR) of 6.6% divided by 12 months since there are 12 months in a year
effective monthly interest=6.6%/12
effective monthly interest=0.0055
FV=PV*(1+r)^N
FV=the balance owed after 5 months=unknown
PV=the loan amount=$2375
r=effectively monthly interest rate=0.0055
N=number of months that have passed since the loan was taken=5
FV=$2375*(1+0.0055)^5
FV=$2,441.03

How long will it take money to double if it is invested at the following rates?
(A) 6% compounded monthly
(B) 10.2% compounded monthly
(A) years
(Round to two decimal places as needed.)
(B) years
(Round to two decimal places as needed.)
The number of years it would take to double at 6% compounded annually is 11.55 years
The number of years it would take to double at 10.2% compounded annually is 6.8 years
What is the doubling time?When an amount earns at a compound interest, it means that the investment increases at an exponential rate. This means that the rate of growth in a new compounding period would be greater than the rate of growth at the previous compounding period.
When an amount is compounded monthly, it means that both the amount invested and the interest that has already been earned increases in value once a month, twelves times a year.
The formula that can be used to determine the number of years it would take the investment to double is:
Number of years it would take to double = In (FV / PV) / r
Where:
FV = future value PV = present value FV / PV = 2 r = interest rater = 6/12 = 0.5%
r = 10.2 /12 = 0.85%
Number of years it would take to double = In2 / 0.005 = 138.629 months
138.629 months / 12 = 11.55 years
Number of years it would take to double = In2 / 0.0085 = 81.547 months

A woman bought S shirts at $20 each and J jerseys at $ 15 each at a total Cost of $ 155. if however she had bought half as many Shirts, and twice as many jerseys, then the total Cost would have been $190. Evaluate S and J.
After solving the set of linear equation so formed, we conclude that value of "S" and "J" is 4 and 5 respectively.
As per the question statement, A woman bought "S" shirts at $20 each and "J" jerseys at $ 15 each at a total Cost of $ 155. However, the total cost would have been $190 if she had purchased half as many shirts and twice as many jerseys. We are supposed to find the value of "S" and "J"
Let us first form the set of linear equation so formed.
Cost of one shirt = $20
Cost of "S" shirts = $20 x S = 20S
Cost of one jersey = $15
Cost of "J" jerseys = $15 x J = 15J
Total cost = $155
20S + 15J = 155 is our first linear equation obtained.
Now if however she bought half as many Shirts, and twice as many jerseys, then the total Cost would have been $190 and the equation formed will be :
20(S/2) + 15(2*J) = 190
or 10S + 30J = 190, is our second equation
This question is a classic example of forming a set of linear equation in two variable out of any given statement.
Solving the two sets of equation we get, S = 4 and J = 5

The coordinates of the vertices of quadrilateral ABCD are (−6,−1), (−5,2), (−1,−5), and (0,−2). Parker states that quadrilateral ABCD is a parallelogram. Prove or disprove Parker’s statement.
As the length of the sides AD ≠ BC the given quadrilateral ABCD is not a parallelogram.
What approach proves the lines are parallel?To prove that the given lines are parallel we have to determine their slope if the slope if equal then the lines are parallell.
We know that a quadrilateral is a parallelogram when opposite lines are of the same length and opposite lines are parallel to each other.
Given a quadrilateral, ABCD has coordinates A(−6,−1), B(−5,2), C(−1,−5), and D (0,−2).
∴ The quadrilateral ABCD t be a parallelogram length of AB = DC and length of AD = BC.
We know the distance formula is [tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].
So, lenght of AB = [tex]\sqrt{ (-5+6)^2 + (2 + 1)^2[/tex].
AB = [tex]\sqrt{ 1 + 9}[/tex].
AB = [tex]\sqrt{10}[/tex] units.
Lenght of DC = [tex]\sqrt{(0+1)^2 + (-2+5)^2}[/tex].
DC = [tex]\sqrt{10}[/tex] units.
Now length of AD = [tex]\sqrt{0+6)^2 + (-2+1)^2[/tex].
AD = [tex]\sqrt{ 37}[/tex] units.
Length of BC = [tex]\sqrt{(-1+5)^2 + (-5+2)^2[/tex].
BC = [tex]\sqrt{25}[/tex].
BC = 5 units.
As BC ≠ AD therefore quadrilateral ABCD is not a parallelogram.
