HELP PLEASE!!!!!!!!!!!!!!
The profit percent for the pencils is equal to 10%.
What is the profit percent of the pencils?If C is the cost and P is the price, then the formula for the profit percent is:
p = 100%*(P - C)/C
Here we know that the selling price of 10 pencils is equal to the cost price of 11 pencils, then we can write the eqation:
10*P = 11*C
We can solve this for P.
P = (11/10)*C = 1.1*C
Replacing that in the given formula we will get:
p = 100%*(1.1*C - C)/C
p = 100%*(1.1 - 1)*C/C

How many answers are there to a system of equations?.
A system of equations is a set of two or more equations with two or more variables. The number of solutions to a system of equations depends on the number of equations and the number of variables.
A system of equations can have one unique solution if the equations are consistent and independent. This means that there is one specific set of values that makes all equations true.A system of equations can have infinitely many solutions if the equations are consistent and dependent. This means that there are infinitely many sets of values that make all equations true. This is usually represented by a line or a plane in the case of systems of 2 or 3 equations with 2 or 3 variables.A system of equations can have no solution if the equations are inconsistent. This means that there are no values that can be assigned to the variables that make all equations true.It's important to note that the number of solutions is not determined by the number of equations, but by the relationship between the equations and the variables.

What is the formula of distributive property?.
The formula of distributive property is the following, a(b+c) = ab + ac , where a,b,c are real numbers.
The distribution property of multiplication over addition applies when values are multiplied by sums. The expression for the distribution characteristic is expressed as: a × (b + c) = (a × b) + (a × c); where a, b, and c are the operands. The numbers outside the brackets are multiplied by each term inside the brackets and the products are added. For example, you want to multiply the sum of 20 + 3 by 9. Since we have similar terms, we usually add numbers first and then multiply by 5. But according to the property, we can first multiply each summand by 5, so 5( 20 + 3)
= 5 × 20 + 5 × 3
= 100 + 15 = 115.

What is the value of an in 3 7 is equal to 25?.
The value of 'n' in the equation 3n + 7 = 25 is equal to 6.
In the equation 3n + 7 = 25, 'n' is a variable representing an unknown value. To find the value of 'n', we need to isolate it on one side of the equation.
The first step is to remove the constant term 7 from the equation. This can be done by subtracting 7 from both sides of the equation, which gives:
3n = 18
The next step is to get 'n' alone on one side of the equation. This can be done by dividing both sides of the equation by 3, which gives:
n = 18/3
n = 6
So the value of 'n' in this equation is 6.

How the commutative property works with addition?.
If two numbers A and B are given, then the formula of the commutative property of numbers for addition is given as: A + B = B + A
The commutative property deals with the arithmetic operations of addition and multiplication. It means that changing the order or position of two numbers while adding or multiplying them does not change the end result.
For example, 4 + 5 gives 9, and 5 + 4 also gives 9. The order of two numbers being added does not affect the sum.
As a result, the commutative property is concerned with moving the numbers about. So, if altering the order of the operands has no effect on the result of the arithmetic operation, that arithmetic operation is commutative.

What is the slope of y =- 10x 1?.
The slope of y=-10x is -10.
The slope of a linear equation in the form of y = mx + b is represented by the coefficient of x, which is also known as the "slope" or "rate of change." In this case, the coefficient of x is -10.
This means that for every unit increase in x, there is a corresponding decrease of 10 units in y. In other words, the line represented by this equation has a negative slope, meaning it slopes downwards as it goes from left to right.
A linear equation is an equation that can be written in the form of y = mx + b, where m is the slope (or rate of change) and b is the y-intercept (the point where the line crosses the y-axis). Linear equations represent straight lines on a graph, and their slope and y-intercept can be used to determine the characteristics of the line, such as its direction and position.

How to solve a nonlinear system of equations
In this problem we find the case of a system of two equations formed by a linear equation and a quadratic equation that can be solved by means of algebra properties. First, write the entire system of equations:
3 · x - y = 4
2 · x² + y² + x · y = 6
Second, clear y in the first equation:
y = 3 · x - 4
Third, substitute in the second equation:
2 · x² + (3 · x - 4)² + x · (3 · x - 4) = 6
2 · x² + 9 · x² - 24 · x + 16 + 3 · x² - 4 · x = 6
14 · x² - 28 · x + 10 = 0
By quadratic formula:
x₁ = 1 + √14 / 7 or x₂ = 1 - √14 / 7
Fourth, find the possible values for y:
y₁ = 3 · x₁ - 4
y₁ = 3 · (1 + √14 / 7) - 4
y₁ = - 1 + 3√14 / 7
y₂ = 3 · x₂ - 4
y₂ = 3 · (1 - √14 / 7) - 4
y₂ = - 1 - 3√14 / 7
Fifth, write the solutions:
(x₁, y₁) = (1 + √14 / 7, - 1 + 3√14 / 7), (x₂, y₂) = (1 - √14 / 7, - 1 - 3√14 / 7)
