The solution to the equation -1/5 = -2y + 8/5 is y = 9/10

Given the equation in the question;

-1/5 = -2y + 8/5

First, rewrite the equation as;

-2y + 8/5 = -1/5

Move all terms not containing y to the right side of the equation

-2y + 8/5 - 8/5 = -1/5 - 8/5

-2y = -1/5 - 8/5

Add  -1/5 and -8/5

-2y = ( -1 - 8) / 5

-2y = -9 / 5

Divide both sides by -2

-2y / -2 = -9/5 ÷ -2

y = -9/5 × -1/2

y = 9/10

The equation that represents the total amount the fan paid is

32 x (P + 25) = 3,232.

The amount spent by the friend is $909.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 8 is an equation.

We have,

Amount spend for 32 tickets = $3,232

Cost of parking = $25

Let p represent the amount the fan paid for each ticket.

The cost of each ticket.

32 x (P + 25) = 3,232

Solve for P.

There are 4 kilograms of type B in one bag of the blend.

What is a linear equation in one variable?

A linear equation in one variable is an equation that can be written in the form ax + b = 0, where a and b are constants and x is the variable. This equation represents a straight line in a coordinate plane and the solution to the equation corresponds to the x-coordinate of the point where the line intersects the x-axis.

Let's call the amount of type B in one bag of the blend "x".

Since one bag of the blend is 4 kilograms of type A, we know that one bag is 4 + x kilograms of coffee.

And since 6 bags of the blend is a total of 48 kilograms, we can write an equation:

6 * (4 + x) = 48

Expanding the left-side of the equation:

24 + 6x = 48

Subtracting 24 from both sides:

6x = 24

Dividing both sides by 6:

x = 4

Hence, there are 4 kilograms of type B in one bag of the blend.

The amount invested in savings with annual interest rate of 6% and 10% is $398200 and $199100.

Simple Interest (S.I.) is a way for figuring out how much interest will accrue on a specific principal sum of money at a certain rate of interest. For instance, if someone borrows Rs. 5000 at a rate of 10 p.a. for two years, they will pay S.I. on the borrowed money for those two years.

Let S be his savings.

He divided S into x that goes at 6% and y at 10%

As he put twice as much at the lower-yielding one, x = 2y.....(1)

Simple interest is given by: Amount x interest x time

Thus,

SI₁ = x . 0.06 . 1 = 0.06x

S I₂ = y. 0.10 . 1 = 0.10y

As x = 2y, I₁ = = 0.06 . 2y = 0.12y

As we know that the annual interest was $3982

SI₁ + SI₂ = 3982

0.12y + 0.10y = 3982

0.22y = 3982

y = 3982/0.22

y = 18100

As x = 2y, x = 36200

By solving a system of equations, wewill see that they sold 325hamburgers.

Let's define the variables:

h = number of hamburgers.

c = number of cheeseburgers.

We know that the total combined number is 588, then we can write:

h +c = 588

And there were 62 fewer cheeseburers than hamburgers, then:

c = h - 62

Now we have a system of equations:

h +c = 588

c = h - 62

c is already isolated on the second equation, so we can replace that on the first equation to get:

h + (h - 62) = 588

2h = 588 + 62

2h = 650

h = 650/2 = 325

The Angle C is 83.2°

The Law of Cosines, also known as the Cosine Formula, is a mathematical relationship that relates the lengths of the sides of a triangle to the cosine of one of its angles. The law states that in a triangle ABC with sides a, b, and c opposite to angles A, B, and C, respectively, the following equation holds:

c^2 = a^2 + b^2 - 2ab cos(C)

where "cos" represents the cosine function. The Law of Cosines can be used to find missing sides or angles in a triangle when given sufficient information. It is widely used in geometry, trigonometry, and engineering. The Law of Cosines is an extension of the Pythagorean theorem and can be used when the triangle is not a right triangle. It is a powerful tool for solving a variety of problems in a wide range of fields.

To find the angle C in triangle ABC, you can use the Law of Cosines. The Law of Cosines states that in a triangle ABC with sides a, b, and c and opposite angles A, B, and C, the following equation holds:

c² = a² + b² - 2abcos(C)

In this case, a = 20 cm, b = 29 cm, and c = 24 cm, and we are given that angle BAC = 82 degrees. Using this information, we can calculate cos(C) as follows:

cos(C) = (a² + b² - c²)/(2ab) = (20² + 29² - 24²)/(2×20×29) = 0.2618

Finally, we can use the inverse cosine function (arccos) to find angle C:

C = arccos(cos(C)) = arccos(0.2618) = 83.2 degrees (rounded to one decimal place).

So, angle C in triangle ABC is approximately 83.2 degrees.

  (a)  y = x/3 -1

Step-by-step explanation:

You want the equation of the line graphed showing points (3, 0) and (6, 1).

The slope of the line is its "rise" divided by its "run." Here, the points are 3 units apart horizontally, and 1 unit vertically, with the line going up to the right. That means ...

  slope = rise/run = +1/+3 = 1/3

The slope-intercept form of the equation for a line is ...

  y = mx +b . . . . line with slope m and y-intercept b

The slope of 1/3 means the coefficient of x will be 1/3. There is only one answer choice like that:

Therefore , the solution of the given problem of speed comes out to be

speed of freight train is 10 mi/h.

We can determine how fast that anything is traveling by looking at it from a distance. The amount of distance an object can go in a given length of time depends on its speed. Velocity is calculated using the formula velocity = distance/time. The three most used units of speed are meters per second (m/s), kilometers per hour (km/h), and miles per hour (mph) (mph).

Here,

Given :

passenger train covers a distance of 175 mi.

Answer:

(x - 6)² + y² = 36 and x2 + (y + 6)2 = 36.

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r is given by:

(x - h)² + (y - k)² = r².

So, for a circle with a diameter of 12 units, the radius is 6 units.

For the center of the circle to lie on the y-axis, the x-coordinate, h, is 0.

So, the equation for a circle with center (0, k) and radius 6 units is:

(x - 0)² + (y - k)² = 6²

x² + (y - k)² = 36

Two possible values for the y-coordinate of the center, k, that would give us two different circles are k = 6 and k = -6.

So, the two equations are:

x² + (y - 6)² = 36
