The nearest ten of 555 is 550.

The number system or the numeral system is the system of naming or representing numbers. We know that a number is a mathematical value that helps to count or measure objects and it helps in performing various mathematical calculations.

In mathematics, there are various number systems such as the decimal number system, binary number system, octal number system, and hexadecimal number system.

Round the number to the nearest ten. 555 is between 550 and 560.

Looking at the 1 in the one's place. It's equal to 5, so round down to either 550 or 560. In this case, either one can be correct.

Thus, the nearest ten of 555 is 550.

The pair of linear equations 3x + 4y + 5 = 0 and 12x + 16y + 15 = 0 has no solution.

To find the number of solutions that a pair of linear equations will have, we can use the concept of the ratio of coefficients.

For the pair of linear equations:

3x + 4y + 5 = 0

12x + 16y + 15 = 0

We can find the ratio of the coefficients of x in both equations.

In the first equation, the coefficient of x is 3 and in the second equation, the coefficient of x is 12. The ratio of these coefficients is

3/12 = 1/4

We can also find the ratio of the coefficients of y in both equations.

In the first equation, the coefficient of y is 4 and in the second equation, the coefficient of y is 16. The ratio of these coefficients is

4/16 = 1/4

As both ratio are equal, let us check ratio of constants.

5/15 = 1/3

So the ratio of constants is not equal, so there is no solution for this system of linear equations.

An inequality depicts the relationship between two values in an algebraic statement that are not equal.

Inequality, a declaration of the relation of greater, greater than or equal to, smaller, or less than or equal to between two numbers or algebraic expressions.

An inequality is a claim that demonstrates the connection between two (or more) expressions that have one of the following five signs:,, >,,. Similar to an equation, an inequality can be true or untrue. A true statement is: 34 - 12 > 5 + 2. An incorrect statement is 1 + 3 6 - 2.

When two values in an algebraic expression are not equal, an inequality illustrates their relationship. One of the two variables on the two sides of the inequality can be represented by an inequality sign as greater than, greater than or equal to, less than, or equal to another value.

The mistake made is the error in finding the value of the slope, m, of the line.

The error can be corrected by plugging in m = 6/3 = 2 in the equation; y = m·x + b

The slope of a line is the ratio of the rise to run of the points on the graph of the line.

The points on the graph of the line are; (0, -2), and (3, 4)

The slope of the line, m, can be found using the formula;

m = (y₂ - y₁)/(x₂ - x₁)

Where for the line in the question, we get;

Therefore;

Slope, m = (4 - (-2))/(3 - 0) = 6/3 = 2

The slope of the line = 2

The equation of the line in point-slope form is therefore;

(y - 4) = 2·(x - 3)

y = 2·x - 6 + 4 = 2·x - 2

y = 2·x - 2

The equation can also be found using the x-intercept as follows;

At the x-intercept, x = 0. The x-intercept is therefore, the point (0, -2)

The equation of the line in the slope-intercept form is, y = m·x + b, where b is the y-value at the x-intercept is therefore;

y = -2, when x = 0

-2 = 2×0 + b

b = -2

y = m·x + b, therefore; y = 2·x - 2

The mistake of the student is therefore;

y = m·x + b

4 = 2·(3) + b

4 = 6 + b

The rational expression that is equal to 4(x-1)/(x-1)(x+5) is 4/(x+5).

What are rational expressions ?

Rational expressions represent the relationship between two polynomials. It signifies that the numerator and denominator are both polynomials in it. It is an algebraic expression ratio with an unknown variable, similar to a fraction. We may, however, simplify this type of equation with the aid of a calculator.

Addition and subtraction: When adding or subtracting rational expressions with the same (or similar/common) denominator, keep the denominator alone. If possible, reduce the remaining expression.

If the rational expressions have different denominators, then LCM is applied first. Change each rational expression to its equivalent by changing the denominator exactly. Finally, combine or delete similar phrases. If feasible, reduce the remaining expression.

Multiplication: Factor the polynomial numerators and denominators (if any exist); then reduce wherever possible. Reduced form is obtained by multiplying the remaining numerators and denominators independently.

Division: Invert the denominator (or divisor) and multiply it with the first rational expression (i.e. dividend or numerator) since reduction can only be done simply after changing the division into multiplication, as with fractions. As previously demonstrated, further simplification is equivalent to multiplication.

Now ,

Given rational expression is =4(x-1)/(x-1)(x+5)

=4/(x+5)                   ( x-1 is same in numerator and denominator so cut it)

Final Rational expression = 4/(x+5)

Answer: If Zendaya invests $70 in an account paying a simple interest of 7.3% per year, and no money will be added or removed from the investment, she will have $75.11 in one year.

To calculate the amount of interest earned, you can use the formula:

Interest = Principal x Rate x Time

where

Principal = $70

Rate = 7.3/100 (expressed as a decimal)

Time = 1 year

So the interest earned is:

$70 x 0.073 x 1 = $5.11

To find the total amount at the end of the year, you add the interest to the original principal:

$70 + $5.11 = $75.11

The factor of negative 1 will be -1

Now, According to the question:

What is factor?

A factor is a number that divides another number, leaving no remainder. In other words, if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product because they are divisible by the product.

There are two methods of finding factors: multiplication and division. In addition, rules of divisibility may also be used.

Hence, Every negative number can be thought of as having some positive factors and exactly one negative factor, -1. When a positive number and a negative number are multiplied, the product has that one -1, so it's negative.

Sarah and Joshua both use correct trigonometry expressions to find out the height of garage wall.

Sarah and Joshua serving to estimate the height of a parking garage using a 50 yards-long rope.

Joshua is in the floor while Sarah stands on the top of garage. Each holds an end of the rope. Joshua walks away until the rope is completely tense,

making an angle of 30° with the floor and an angle 60° with the top.

Joshua determined the height of the wall is 25 yards with the help of trigonometry expression for Sin, and Sarah determined by Cos.

So, let us examine whose approach is correct,

We have length of rope is 50 yards and the angle with floor is 30 and angle with top is 60°

first examine the approach of Joshua,

according to trigonometry, we have

[tex]Sin\theta=\frac{perpendicular}{hypotenuse}[/tex]

[tex]Sin30=\frac{h}{50}[/tex]

[tex]\frac{1}{2} =\frac{h}{50}[/tex]

To translate a graph down and right, you would take each point on the graph and move it down and to the right by a given number of units. To be more specific, you would add the given number of units to the x-coordinate and add the given number of units to the y-coordinate.

A graph can be translated down and right by taking each point on the graph and moving it down and to the right by a given number of units. This means that for each point on the graph, the x-coordinate will be increased by the given number of units and the y-coordinate will be increased by the same number of units. This type of translation is often used to move a graph from one position to another on the coordinate plane. It can also be used to create a graph that is shifted from its original position. This shifting of the graph can be used to compare two different graphs or to move a graph to the origin.

Now, According to the question:

Siti opened her money box to find 50 pieces of $5-notes and $2-notes.

If the total value of all the notes is more than $132.

To find the minimum number of $5-notes she has
