Answers

Answer 1
Answer:

The number 15 times 3 is equals 45.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Now, We know that;

⇒ 15 × 3

⇒ 45

Hence, 15 times 3 is equals 45.

The equation of a circle whose center is not at the origin is given by the equation:

(x-h)^2+(y-v)^2=r^2

Where:

\bullet \ (h,v) \ is \ the \ center \n \n \bullet \ r \ is \ the \ radius

According to the provided equation:

(x-10)^2+(y-10)^2=10^2

By comparing this equation with the previous one, we can assure that the radius is:

\boxed{r=10}

When solving a system of equations, how do you determine which method to use?

Answers

The method to solve an equation is

There are three methods used to solve systems of equations: graphing, substitution, and elimination

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

The three methods used to solve systems of equations: graphing, substitution, and elimination

Solving an equation by Graphing :

Simply graph the provided equations and discover the point(s) where they all cross to solve a system. The coordinate of this point will provide you with the values of the variables you are attempting to solve for. This works well when the equations are already in slope-intercept form.

Solving an equation by Substitution:

Substitution is best used when one of the equations is in terms of one of the variables. Once an expression for the variable has been found, substitute or plug it into the other equation where the original variable was to solve for the next variable's integer value. The final step is to substitute the discovered number value for its corresponding variable in the original equation.

Solving an equation by Elimination:

Elimination is the process of combining the equations to obtain an equation with only one variable. This is only possible if the coefficients of one variable in both equations are diametrically opposed and will cancel each other out when put together.

The next step would be to use the equation we devised to determine the variable's value, and then plug that value back into the original equation to determine the remaining variable.

Substitution is best to use one one or both equations is already solved for one of the variables. Elimitation can be use if all variables have a coefficient other than 1.
