57
When you see 'sum' it means add (+) Thus 17+20 = 37
If the question is, "What two numbers sum to 37 and have a difference of 3?" Then the answer is 20 and 17 To solve the problem, call the two numbers a and b. Then a + b = 37 therefore b = 37 - a. And a - b = 3 : substitute the value (shown above) for b in this equation. a - (37 - a) = 3 : 2a - 37 = 3 : 2a = 3 + 37 = 40 : a = 20 As a + b = 37 then 20 + b = 37 : b = 37 - 20 = 17
8 + 9 + 20 = 37.
To find the sum of all prime numbers between 20 and 40, we first list out the prime numbers in that range: 23, 29, 31, 37. Then, we simply add them together: 23 + 29 + 31 + 37 = 120. Therefore, the sum of all prime numbers between 20 and 40 is 120.
The sum of 37 and 58 is 95.
It is 37.
-33
The sum is -80.
1, and 37 are the factors that will give you a sum of 38
54 + 37 = 91
21 + 37 = 58
Sum(X) = 37 Sum(X2) = 289 Var(X) = Sum(X2) - sum(X)2/n = 289 - 37*37/5 = 15.20
