Therefore , the solution of the given problem of equation comes out to be 12 pennies.

A equation is a method that links two statements and signifies equivalence with the equals sign (=). In algebra, a scientific assertion that confirms the equivalency of two schemas is referred to as an equation. For instance, the answer obd + 6 = 12 has an equal sign between the elements ptdc + 6 and 12, respectively. There is a mathematical formula that describes the relationship between two phrases on either side of a letter. Frequently, the symbol and the single variable are the same. For example, 4x – 4 = 0.

Here,

Solving once per variable is the key to this issue.

Let x equal quarters and y equal dimes.

So, x + y = 20

Now, we'll build an equation using the coin values and total quantity of cash. (Decimals have been omitted for clarity.) 25x + 10y = 320

In terms of y, let's restate the original equation: y = 20 - x

In the second equation, we will now substitute this for y. 25x + 10(20-x) = 320

Calculate the value of x: 25x + 200 – 10x = 320.

15x = 120

8 quads times x

In light of this, y = 20 - 8 = 12 pennies.

Therefore , the solution of the given problem of equation comes out to be 12 pennies.

What is the slope-intercept form?

The slope-intercept form is a way of expressing a linear equation in the form of y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept is the point at which the line crosses the y-axis, meaning the point at which the line intersects the y-axis when x = 0.

The given equation is in the form of y = mx + b where y =27, m = 3 and b = 1, is a linear equation and it can be represented as a straight line in a coordinate plane.

In the given set of data, 4/5 is the constant of proportionality in the proportional relationship.

When two or more parameters are either directly or indirectly proportional to one another, the relationship is written as a = kb or a = k/b, where k denotes the direction of the relationship between the two variables. The proportionality constant, k, is defined as follows.

The ratio of two proportional values at a constant value serves as the definition of the proportionality constant. When the product or ratio of two variables yields a constant, the relationship between the two is proportional. By comparing the ratio of the two specified quantities, we can calculate the value of the proportionality constant. A direct variation or an inverse variation of this relationship are both possible.

Given

2 : 5/2

2 = (k)5/2

also

3 : 15/4

3 = (k)15/4

This gives us

k = 2 × 2/5

k = 4/5

k = 3 × 4/15

k = 4/5

Distance is a measure of how far an object has traveled from a starting point. Displacement is the change in position from the starting point.

It is the total distance an object has moved and is the sum of all the displacements an object has made. The formula for calculating distance is distance = speed x time. For example, if a car has traveled at a speed of 50 km/h for 4 hours, then the distance traveled is 200 km (50 km/h x 4 h = 200 km).

Displacement is the change in position from the starting point. It is the shortest distance between the starting point and the final point and does not take into account the direction of motion. The formula for calculating displacement is displacement = final position – initial position. For example, if a car starts at point A and travels to point B, the displacement is the distance between A and B (B – A).

The value of CE in the segment is 30 units.

The value of x in the segment is 1 units.

A line segment is bounded by two distinct points on a line. Therefore, point D is located on the segment CE. Hence,

CD = 24 and DE = x

CE = 5x

Therefore, the measurement of the segment CE can be found as follows:

CE = CD + DE

5x = 24 + x

5x - x = 24

4x = 24

divide both sides of the equation by 4

x = 24 / 4

x = 6

Finally,

CE = 5(6) = 30

The segment XZ is bisected by the point Y. Hence,

1. Slope-intercept form: y = mx + b

2. Point-slope form: y - y1 = m(x - x1)

3. Standard form: ax + by = c

1. Slope-intercept form: y = mx + b - This is the most common form of a straight line; it is composed of two parts: m (the slope of the line) and b (the y-intercept). To use this form, you need to know the slope (m) of the line and the y-intercept (b). From this information, you can calculate the equation of the line by substituting the values of m and b into the equation.

2. Point-slope form: y - y1 = m(x - x1) - This form of a straight line requires two points on the line and the slope of the line. To use this form, you need to know the two points on the line (x1, y1) and the slope of the line (m). Then, you can calculate the equation of the line by substituting the values of x1, y1 and m into the equation.

3. Standard form: ax + by = c - This form of a straight line is composed of three parts: a (the coefficient of x), b (the coefficient of y) and c (the constant).

The additive inverse of -13 7/8 is +13 7/8.

The additive inverse of a number is the number that, when added to the original, equals zero. The additive inverse of -13 7/8 can be found by turning the sign of the original number into its opposite, which would be +13 7/8. This can be expressed mathematically using the formula a + (-a) = 0, where a is the original number.

When -13 7/8 is added to +13 7/8, the result is 0. This can be seen by calculation: -13 7/8 + 13 7/8 = -13 7/8 + 8/8 + 5/8 = -5/8 + 8/8 = 3/8 + 8/8 = 11/8 + 8/8 = 19/8 + 8/8 = 27/8 + 8/8 = 35/8 + 8/8 = 43/8 + 8/8 = 51/8 + 8/8 = 59/8 + 8/8 = 67/8 + 8/8 = 75/8 + 8/8 = 83/8 + 8/8 = 91/8 + 8/8 = 99/8 + 8/8 = 107/8 = 0.

The number 9550000 can be arranged in a total of 8!/(4!4!) = 70 different ways.

Digits are numerals or numbers used for counting, measuring, and representing quantities. They are the building blocks of mathematics, and are used to express amounts, relationships, and orders of magnitude. Digits are also used in computers and other digital devices to store and communicate information.

The 8 digits of 9550000 can be arranged using the formula for permutation: nPr = n!/(n-r)!

In this case, n = 8 and r = 8. So, the number of permutations of the 8 digits of 9550000 will be 8!/(8-8)! = 8!/(0!) = 8! = 40320.

However, we need to account for the fact that there are 4 zeros in the number 9550000. To do this, we need to divide the number of permutations by 4! (factorial of 4) to account for the 4 identical digits.

Therefore, the total number of ways the digits in the number 9550000 can be arranged is 40320/4! = 70.
