The installment price is $55.

This can be illustrated through an expression. Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both.

An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles. Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Here, you buy an I-phone for $800 or pay $75 down and the balance in 12 monthly payments of $65. The total amount will be:

= 75 + (12 × 65)

= $855

The installment will be:

= $855 - $800

= $55

Step-by-step explanation:

Equation

[tex]3n + 11 = 38[/tex]

3n=38-11

n=27/3

n=9

therefore triplets are 9 years old

Check

[tex]3n + 11 = 38[/tex]

[tex]3 \times 9 + 11 = 38 \\ 27 + 11 = 38 \\ 38 = 38[/tex]

Answer:

equation: 3n+11=38

The triplets are 9 years old.

Step-by-step explanation:

3n : triplets x their age

11 : the sum

38 : the sum of the ages

We must isolate n to know their age so,

<=> 3n+11=38

<=> 3n=38-11

<=> n=(38-11)/3

<=> n=9

Hello,

I hope you and your family are doing well!

To find the value of x, we can use the fact that TL is the perpendicular bisector of BE. This means that TL splits BE into two segments of equal length. Therefore, we have:

EL + BF = BE

Substituting the values for EL, BF, and BE gives:

[tex](8x - 17) + (7x - 5) = (3x + 6)[/tex]

Combining like terms gives:

[tex]15x - 22 = 3x + 6[/tex]

Subtracting 3x from both sides gives:

[tex]12x - 22 = 6[/tex]

Adding 22 to both sides gives:

[tex]12x = 28[/tex]

Dividing both sides by 12 gives:

[tex]x = 28/12 = 7[/tex]

Now that we know the value of x, we can use this value to find the value of y. We can use the equation TE = 2x - 10 to find the value of TE:

TE = 2x - 10 = 2 * 7 - 10 = 14 - 10 = 4

Now we can use the equation EL = 8x - 17 to find the value of EL:

EL = 8x - 17 = 8 * 7 - 17 = 56 - 17 = 39

Since TL is the perpendicular bisector of BE, the length of TL is the average of the lengths of EL and TE. The average of EL and TE is:

(EL + TE)/2 = (39 + 4)/2 = 43/2 = 21.5

So the length of TL is 21.5, and the value of y is 21.5 and x is 7

The account's APY is 5.12%.

Annual Percentage Yield, or APY, is the rate that may be earned on an account over the course of a year and includes compound interest.

The annual percent yield, or APY, accounts for interest compounding. Because it takes into account the interest you earn on your money, it accurately reflects the interest rate you really receive on an investment.

Consider the previous illustration, where a $100 investment generates a 5% quarterly compounded return. On the $100, you receive interest throughout the first quarter. However, in the second quarter, you also receive interest on the $100 in addition to the first quarter's interest.

The APY (Annualized Percentage Yield) formula is:

APY = [tex](1+i/N)^{N} -1[/tex]

where, i = Nominal rate = 5%, N = Number of compounding periods = 12

putting the values in the above formula, we get,

APY = (1 + 5% / 12)^12 - 1

APY = (1 + 0.4167%)^12 - 1

APY = (1 + 0.0041667)^12 - 1

APY = (1.0041667)^12 - 1

APY = 1.051161897 - 1

APY = 0.051161 or 5.12%

The APY for this account 5.12%

What is graph?

A graph is a structure that resembles a set of items in discrete mathematics, more especially in graph theory, in which certain pairs of the objects are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

Note that the distance between two points is equal to the length of the line segment that joins them.

So now we already have answers for two of the boxes.

The difference in the x-coordinates gives us the horizontal distance between the two points, while the difference in the y-coordinates gives us the vertical distance between the points.

The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis. Key Point. The equation of a straight line with gradient m and intercept c on the y-axis is y = mx + c.

The equation of a line that passes through the point (2, 6) and has a slope of -1/2 can be written in the form y = mx + b, where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.

To find the equation of the line, we can use the point-slope form of a line, which is given by the equation y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line.

Substituting the values for the point and the slope into this equation, we get:

We can solve this question by using Pythagoras Theorem . The value of x in the given question is 8√3.

The well-known Pythagorean Theorem, which states that the square of the hypotenuse is equal to the sum of squares of the lengths of the other two sides of the right-angled triangle, states that the square on the hypotenuse (the side opposite the right angle) is equal to the square on the legs of a right triangle. Pythagorean Theorem is written as a2 + b2 = c2. Alternatively, the square of the hypotenuse of a right triangle is equal to the sum of the squares of its two legs.

From the given triangle using Pythagoras theorem,

       Assume the triangle as ABC where AB=y BC=z and AC=28

        D is the altitude from B and BD=x

         AD=12 so CD=16

Now using Pythagoras theorem,

           (y)2 = (12)2 + (x)2 - eq1

           (z)2 = (x)2 + (16)2 -eq2

           (y)2 + (z)2 =(28)2 -eq3

  Substitute eq 1 and 2 in 3

Answer: The correct equation to find the cost, c, of each cello lesson is: 15c + 35 = 425

Step-by-step explanation:

This equation represents the total cost of the cello lessons and the cello rental, which is 425 dollars. The cost of the cello lessons is represented by 15c, and the cost of the cello rental is represented by 35 dollars. By solving this equation for the variable c, we can find the cost of each cello lesson.

To solve this equation, we can use the following steps:

Subtract 35 from both sides of the equation: 15c = 425 - 35

Simplify the right side of the equation: 15c = 390

Divide both sides of the equation by 15: c = 390/15

Simplify the right side of the equation: c = 26

Therefore, the cost of each cello lesson is $26.

Step-by-step explanation:

Given equation:

When completing the square for a quadratic equation, the first step is to move the constant to the right side of the equation:

[tex]\implies t^2-10t+6-6=7-6[/tex]

[tex]\implies t^2-10t=1[/tex]

Add the square of half the coefficient of the term in x to both sides to form a perfect square trinomial on the left side:

[tex]\implies t^2-10t+\left(\dfrac{-10}{2}\right)^2=1+\left(\dfrac{-10}{2}\right)^2[/tex]

Simplify:

[tex]\implies t^2-10t+\left(-5\right)^2=1+\left(-5\right)^2[/tex]

[tex]\implies t^2-10t+25=1+25[/tex]

[tex]\implies t^2-10t+25=26[/tex]

Factor the perfect square trinomial on the left side:

[tex]\implies (t-5)^2=26[/tex]

Square root both sides:
