What sum of two numbers is 8 and their difference is 12 Find the numbers?
Let X be one number and Y the other. So, X + Y = 8 and X - Y = 12 Solve the set of equations simultaneously or use substitution method. X + Y = 8 X - Y = 12 (ADD THIS EQUATION TO FIRST ONE) _______________ 2X = 20, So X =10 and solving for Y using either equation, Y = -2
What is 2y-2x-8 3y-18-3x using elimination method?
To solve this system of equations using the elimination method, we need to eliminate one variable by adding or subtracting the two equations. By looking at the equations given (2y-2x-8 = 0 and 3y-18-3x = 0), we can choose to eliminate either the x or y variable. Let's choose to eliminate the x variable: Multiply the first equation by 3 and the second equation by 2 to make the coefficients of x the same: 6y - 6x - 24 = 0 6y - 36 - 6x = 0 Now we can subtract the second equation from the first equation to eliminate x: (6y - 6x - 24) - (6y - 36 - 6x) = 0 Simplify to get -12 = 0, which is a false statement. Therefore, the system of equations is inconsistent and has no solution.

What is the GPA for 84.44 percent on a 4.0 grade point scale?
Step 1: Find the variable for the unknown GPA value (X) using this cross-multiplication formula: X/84.4 = 4.0/100.0 Multiply the numerator in the first fraction (X) with the denominator in the second fraction (100.0), then multiply the denominator in the first fraction (84.4) with the numerator in the second fraction (4.0). This will give you: 100.0X=337.76 Step 2: Now, you must separate X from 100. Since 100X is multiplication, divide the equation by 100. This gives you 100X/100, where the 100's cancel each other out, leaving only the X. In order for the equation to keep its balance, you must also divide the other side of the equation by 100. So, divide calculate 337.76/100, and you get 3.3776. This leaves the equation as X=3.3776 So, an average of 84.4 = 3.3776 on a 4.0 scale.
How are Richard Dedekind's theories used today?
Richard Dedekind's theories on the foundations of mathematics, particularly his work on defining real numbers using cuts, are still relevant and used in the field of mathematics today. Dedekind cuts are a fundamental concept in analysis and set theory, forming the basis for modern treatments of real numbers and their properties. His contributions continue to influence mathematical research and education.
