the sum of two whole numbers are 77 .their difference is 48.what are the two numbers
Let's denote the two numbers as x and y. Since their sum is 77, we can write the equation x + y = 77. Given that their difference is 29, we have the equation x - y = 29. By solving these two equations simultaneously, we find that the two numbers are 53 and 24.
The numbers 40.5 and 36.5 have a difference of 4 and a sum of 77.
a + b = 77a - b = 1Add the two equations: 2a = 78, a = 39, so 39 - b = 1 : b = 38.Check answer in first eq: 39 + 38 = 77
16,25,36 add to 77. They are the squares of consecutive numbers 4,5,6
Do-it-in-your-head method: 77 minus 29 is 48, half of 48 is 24, 24 add 29 is 53 so your numbers are 24 and 53. Shazam!
11 x 7 = 77
24 and 53.
Geometric Mean of two numbers is the square root of their product, in this case root 77 ie 8.775
The numbers are 38 and 39.
