the sum of two whole numbers are 77 .their difference is 48.what are the two numbers
The square root of 77 is approximately 8.77. The two consecutive whole numbers that lie between this value are 8 and 9.
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!
The two whole numbers that have a difference of 4 and a product of 77 are 11 and 7. You can find these numbers by setting up the equations ( x - y = 4 ) and ( x \cdot y = 77 ). Solving these equations, you can express ( x ) as ( y + 4 ) and substitute it into the product equation, leading to ( (y + 4)y = 77 ). This results in the quadratic equation ( y^2 + 4y - 77 = 0 ), which factors to yield the solutions ( y = 7 ) and ( x = 11 ).
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
