Well, honey, one way to get four fives to equal 30 is to add them all together: 5 + 5 + 5 + 5 = 20. Then, multiply that by the remaining 5: 20 x 5 = 30. Another way is to get creative and arrange the fives like this: (5 + 5) x (5 - 5) = 10 x 0 = 0 + 30 = 30. Voilà!

Oh, dude, I got you. So, one way to get four fives to equal 30 is by adding them together: 5 + 5 + 5 + 5 = 20. Then, just multiply that by another five: 20 x 5 = 30. Another way is to take the square root of 25 (which is 5) and then add another five: √25 + 5 = 5 + 5 = 10. Finally, just multiply that by three: 10 x 3 = 30. Easy peasy!
Well, isn't that just a happy little math problem! To get four fives to equal 30, you can add them together: 5 + 5 + 5 + 5 = 20, then multiply by the remaining 5: 20 x 5 = 30. Another way is to multiply two fives to get 25, then add the other two fives: 25 + 5 = 30. Just remember, there are no mistakes in math, only happy little miscalculations.

No, but eliminating variables is one of several ways to find the value of variables in a system of equations.

To divide a square into 4 equal parts, you can draw two perpendicular lines that intersect at the square's center. This creates four smaller squares of equal size within the original square. Therefore, there is only one way to divide a square into 4 equal parts.
