The average of 4 numbers is 85 in the numbers 76 78 and 81 what number would come next?
Let denote the missing number with x. So we have:(76 + 78 + 81 + x)/4 = 85(235 + x)/4 = 85(4)(235 + x)/4 = (4)(85)235 + x = 340235 - 235 + x = 340 - 235x = 105
How do you solve x 2-18x-4 equals 0 by completing the square?
x² - 18x - 4 = o x² - 18x = 4 x² - 18x + (18/2)² = 4 + (18/2)² x² - 18x + 81 = 4 + 81 (x - 9)² = 85 x - 9 = ±√85 x = 9 ±√85 x = 9 + √85 or x = 9 - √85 if you are still confused, i want you to follow the related link that explains the concept of completing the square clearly.

What number do you add to 86 78 and 92 to make the average 85?
(86 + 78 + 92 + x) / 4 = 85 multiply by 4 on both sides of the equation to get.... (86 + 78 + 92 + x) = 340 Collect like terms.... 256 + x = 340 Subtract by 256 on both sides to solve for x .... x = 84
What are the common factors of 53 and 85?
There are none other than 1. 53 is a prime number, and can only have common factors with a multiple of 53. 53 = 1 x 53 85 = 1 x 85 or 5 x 17 No common factors other than 1, so the GCF would be considered 1.
