What is the equations for a 30-60-90 triangle?
The answer depends on WHAT the equation is about.
What is the system of equations set in order pairs 3x plus 4y equals 38 5x - 5y equals -30?
Simultaneous equations.
What is the x and y coordinates of these equations y equals 3x and 4x plus 2y equals 30?
4x + 2(3x) = 30 10x = 30 x= 3. Y= 9. (3,9)
How do i solve systems of equations by adding or subtracting?
You multiply one equation by some constant, or both equations by different constants, and then add one equation to another (or subtract). Here is an example: 2x + 4y = 30 x + y = 10 Multiplying the second equation by (-2), you get: 2x + 4y = 30 -2x -2y = -20 Now you can add the two equations together, resulting in: 2y = 10 You can solve this for "y"; then you can replace the value you found in any of the original equations to find the corresponding value for "x".
What are equivalant equations?
Equivalent equations are equations that have the same solution set.

What two numbers add up to 21 and multiply 30?
51
The sum of two numbers is 50 their difference is 10 What is the number?
You can experiment with different numbers (trial-and-error). You can also write this as simultaneous equations: a + b = 50 (the sum of the two numbers is 50) a - b = 10 (the difference is 10) There are several approaches to simultaneous equations; in this case, it is easy to solve by adding the two equations together: a + b + a - b = 60 2a = 60 a = 30 So, the first number is 30. You can get the second number by replacing in any of the original equations.
What best describes the solution to the system of equations below?
Which of the following best describes the solution to the system of equations below?3x + 6y = 10 9x + 18y = 30
How do you do minus equations?
For example I have these two equations: A: 3x - 2y = 50 B: x - 2y = 30 If I take A - B, align the equations' terms so the like terms are in one column: 3x - 2y = 50 x - 2y = 30 _________ , So I got (3x -x)= 2x; (-2y - -y) or (-2y + 2y) = 0 ; (50-30) = 20. 2x = 20 => x = 20/2 = 10
Create equations using only 1 2 3 4?
1, 2, 4, 5 = 30
What is the x and y coordinates of these equations y equals 3x and 4x plus 2y equals 30?
4x + 2(3x) = 30 10x = 30 x= 3. Y= 9. (3,9)
What are the different Types of mathematical equations?
Algebraic equations, trigenometric equations, linear equations, geometric equations, partial differential equations, differential equations, integrals to name a few.
