The sum of 20, 30, and 45 is calculated by adding the three numbers together. So, 20 + 30 + 45 = 95. This is because addition is a basic arithmetic operation where you combine the values of the numbers to find the total.
20 + 45 = 65 20 x 45 = 900
600/50 = 12
Let the unknown number be n.Then 20 + n = 30 : Subtract 20 from both sides gives :-20 - 20 + n = 30 - 20 : n = 10
No.
20 + 10 = 30 20 x 10 = 200 200 - 30 = 170 Your answer is 170.
The sum of 30 and 45 is 75.
25 and 20 25 + 20 = 45 25 - 20 = 5
25 and 20 25 + 20 = 45 25 - 20 = 5
20 + 45 = 65 20 x 45 = 900
The words, "sum of" mean 'the added together value of'... For instance, "What is the sum of 15, 20 and 45?" The method is to add each of these figures together: EG. 15 + 20 + 45 The answer, of course, is 80 ... written: 15 + 20 + 45 = 80, or 15+20+45=80
30 and 45

10 + 8 + 20 + 7 = 10 + 20 + 8 + 7 = 30 + 15 = 45
The numbers are 30 and 20.
