Answer:
both are right
Step-by-step explanation:
2/5x = 14
multiply both sides by 5/2:
(5/2)(2/5)x = 14(5/2)
x = 70/2 = 35
However, dividing by 2/5 is the same as multiplying by 5/2, so you are BOTH right. Dividing by a fraction is the same as multiplying by the reciprocal of the fraction.

If the 3rd term of an arithmetic sequence is 2 and the 17th term is -40, find the 7th term
Answer:
-10
Step-by-step explanation:
t3 = a1 + (n - 1)*d
t3 = a1 + (3 -1)*d
2 = a1 + 2d
t17 = a1 + (n - 1)*d
-40 = a1 + 16d Put the first condition underneath and subtract
2 = a1 + 2d
-42 = 14 d
d = - 3
2 = a1 + 2*(-3)
2 = a1 - 6 Add 6 to both sides
2 + 6 = a1
a1 = 8
Now you want the 7th term
t7 = a1 + (n - 1)*d
t7 = 8 + (7 - 1)*d
t7 = 8 + 6*(-3)
t7 = 8 - 18
t7 = - 10

Bethany and Samuel are buying a new house. They have $25,000 saved for a down payment and know that they can afford a monthly payment of $1,500 or less. They also know that the best interest rate they can get is 5.1% annually and they want to sign a 30-year mortgage.
1. This equation is used to find the monthly payment, m, given the monthly interest rate, i, the principal, P, and the number of interest periods, n, in months:
Using the equation, find the largest possible principal P for their situation. In other words, what is the largest amount of money they can borrow? (Hint: To answer the question, you must rearrange the equation.)
The largest amount of money they can borrow is $$276.268.65
How to calculate the largest amount?The main formula used in this problem is the Present Value of an annuity Formula:
P = R[1-(1+i)⁻ⁿ]/i
Where;
P: present value (the mortgage value)R: periodic paymentt: time (in years)r: annual interest ratem: number of compounding per yeari=r/m (rate per period)n=mt the total number of paymentsThe maximal monthly payment that Bethany and Samuel can afford is $1,500.
The best interest rate is %5.1 annually, and they want to sign a 30-year mortgage.
This implies that
R=1,500
t=30
r=%5.1 = 5.1 /100 = 0.051
m=12, because they make the payments monthly
i=r/m=0.051/12=0.00425
n=mt = 12*30=360
That is,
i) they will make 360 monthly payments,
ii) the largest amount of money they can borrow can be found using the formula:
P = R[1-(1+i)⁻ⁿ]/i
Substituting the known values:
P = 1500[1-(1+0.00425)⁻³⁶⁰]/0.00425
Therefore, $276.268.65 is the largest possible principal for the situation

What is unitary method ?
The unit technique is an approach to problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value. The unit method, to put it simply, is used to extract a single unit value from a supplied multiple. For instance, 40 pens would cost 400 rupees, or the price of one pen. The process for doing this may be standardized. a single country. anything that has an identity element.

Center: (2, 8) radius: 3
how do I write the equation of the circle in standard form?
We are given:
Coordinates of center: (2,8)
Radius of circle: 3 units
Finding equation of the circle:
We know that the general form of a circle is:
(x-h)² + (y-k)² = (radius)²
where h is the x-coordinate of the center and k is the y-coordinate
replacing with the given values, we get:
(x-2)² + (y-8)² = (3)²
(Pythagorean Theorem and the Coordinate Plane MC)
Determine the perimeter of the right triangle shown
O 10 units
O 24 units
O 36 units
O 64 unitsl
Answer: 24 units.
Step-by-step explanation: To find the perimeter of a triangle, you need to add the length, width, and hypotenuse. The length and width are provided, but we need to find the hypotenuse of the triangle. To do this, we need to use the Pythagorean Theorem.
The Pythagorean Theorem is basically a^2 + b^2 = c^2 where a and b are the legs of the triangle and c is the hypotenuse (also known as the triangle's longest side). However, whatever answer you get needs to be square-rooted, which is your complete answer. Let's say that the side that's 6 units is leg a and the side that's 8 units is leg b.
6^2 + 8^2 = c^2
36 + 64 = 100
√100 = 10.
Now that we know the hypotenuse, we can add it to our other two sides.
6 + 8 + 10 = 24.
Therefore, 24 is your answer.

Make 4 equal warehouses out of a fence 300 m long. What is the width and length of the sv part if we want them to be the largest possible areas
The width and the length that gives the largest possible areas are 75 meters by 37.5 meters
How to determine the width and the length that gives the largest possible areasFrom the question, we have the following parameters that can be used in our computation:
Number of warehouses = 4
Perimeter of fence = 300 meters
Represent the width with x and the length with y
So, we have the following equations
Area = 4xy
Perimeter = 2(4x + y)
Substitute the known values in the above equation, so, we have the following representation
2(4x + y) = 300
Divide both sides by 2
2x + y = 150
Make y the subject
y = 150 - 2x
Substitute y = 150 - 2x in Area = 4xy
A = 4x(150 - 2x)
This gives
A = 600x - 8x²
Differentiate and set to 0
600 - 16x = 0
So, we have
16x = 600
Divide by 16
x = 37.5
Recall that
y = 150 - 2x
So, we have
y = 150 - 2 x 37.5
Evaluate
y = 75
Hence, the dimensions are 75 meters by 37.5 meters

5 lbs. of organic red potatoes cost
$6.00. What is the price per lb?
Answer:
0.83333333333
Step-by-step explanation:
5 lbs. of organic red potatoes cost $6.00. The price per pound of organic red potatoes is $1.20.
To find the price per pound of organic red potatoes, we can divide the total cost by the weight in pounds.
Price refers to the monetary value or amount that is assigned or charged for a product, service, or commodity. It represents the cost or value that a buyer is required to pay in exchange for obtaining or acquiring something.
Given that 5 lbs. of organic red potatoes cost $6.00, we can set up the following equation:
Price per pound = Total cost / Weight in pounds
Price per pound = $6.00 / 5 lbs.
Dividing $6.00 by 5 pounds gives us:
Price per pound = $1.20
Therefore, the price per pound of organic red potatoes is $1.20.

p = 800, r = 6%, t = 9 year; compounded quarterly
Answer:
The answer is 1367.31 not sure but try it
The amount will be $1367.3 after 9 years.
What is compound interest?Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.
Given that, p = 800, r = 6%, t = 9 year, we need to find the amount if the principal is compounded quarterly,
A = P(1+r)ⁿ
Since, the principal is compounding quarterly, the formula will become,
A = P(1+r/4)⁴ⁿ
A = 800(1+0.06/4)³⁶
A = 800(1.015)³⁶
A = 1367.3
Hence, the amount will be $1367.3 after 9 years.
