a + b = 77
a - b = 1
Add the two equations: 2a = 78, a = 39, so 39 - b = 1 : b = 38.
Check answer in first eq: 39 + 38 = 77
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 difference between 400 and the sum of 821 and 77 can be calculated by first finding the sum of 821 and 77, which is 898. Then, subtract 898 from 400 to find the difference. Mathematically, this can be represented as 400 - (821 + 77) = 400 - 898 = -498. Therefore, the difference between 400 and the sum of 821 and 77 is -498.
37 and 40
Let the numbers equal x and y.... So you have the two equations x+y=77 and 6x=y Using substitution.... x+6x=77 7x=77 x=11 Plugging x back into our original equation.... 11+y=77 y=66 So your two numbers are 11 and 66
Half of 154 is 77, so your numbers are 76 and 78.
the sum of two whole numbers are 77 .their difference is 48.what are the two numbers
The numbers 40.5 and 36.5 have a difference of 4 and a sum of 77.
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.
24 and 53.
The numbers are 38 and 39.
The numbers are 76 and 77.
11 and 66.
81 and 4
65 and 77
The difference between 400 and the sum of 821 and 77 can be calculated by first finding the sum of 821 and 77, which is 898. Then, subtract 898 from 400 to find the difference. Mathematically, this can be represented as 400 - (821 + 77) = 400 - 898 = -498. Therefore, the difference between 400 and the sum of 821 and 77 is -498.
If: 3x+2x = 77 Then: 5x = 77 => x = 15.4 The numbers which are not integers are: 46.2+30.8 = 77
