"Size" is ambiguous, so I'm giving you two answers.

When you hear that a TV is 40 inches, the length from one corner to the opposite corner diagonally is 40 inches. To solve, we use formula for hypotenuse, a^2 + b^2 = c^2.

20^2 + 25^2 = 32.02^2.

If that is what they mean by size, your answer is 32.02. However, size could refer to the area of the screen, which is calculated by length * width.

20 * 25 = 500

The answer in this case is 500.

Answer:

?=19

x=30

Step-by-step explanation:

5/6x - 1/5x = 19

5(5/6x) - 6(1/5x) = 19

25/30x-6/30x=19

19/30x=19

19x=19(30)

19x=570

x= 570/19

x=30

NikAS [45]
The difference of these numbers (32) is also a divisor of both, so that is the greatest common divisor (GCD) and the answer to your question.

The orchard can consist of 32 rows, each with 3 peach trees and 2 cherry trees.
