15 + w expresses the sum of 15 and w
If you mean that the sum of the two numbers is 20 and the product is 75, then X+Y=20 and XY=75 solving for Y and substituting: Y=20-X and XY=X(20-X) then X(20-X)=75 and 20X-X2=75 (20X-X2)-(20X-X2)=75-(20X-X2) then X2-20X+75=0 factoring (X-5)(X-15)=0, so X=15 or X=5 if X=5, then Y=75/X=15 if X=15, then Y=75/X=75/15=5
The sum of all integers from 1 to 20 inclusive is 210.
The exterior angles sum to 3600 , but the interior angles sum to 23400.
The sum means the result of adding the numbers. Therefore the sum of 20 and 15 is 35. 5 times 35 is 175 - therefore 5 multiplied by the sum of 20 and 15 is 175.
It is: 5+15 = 20
The sum of -5 and 20 is 15. The distance between -5 and 20 is 25. The sum of the numbers between -5 and 20 is 180. The sum of the numbers from -5 to 20 is 195.
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
The sum of 18 and 15 is 33. 10+10=20 & 8+5=13. 20+13=33.
The two numbers are 25 and 15
4/20 + 15/20 = 19/20
The two numbers are 5 and 15. 5 + 15 = 20. 15 - 5 = 10.
20+(-15)=5You just took 15 from 20. When adding negative numbers to positive ones, you move LEFTWARD on the number line toward 0 (because that's where the negative numbers are).As I understand the question:If 20 and a number (x) = a negative 15 (-15), then you can write it out as an equation to get the answer:20 + x = -15 is the equation (x represents the number)20 - 20 + x = -15 - (-20) (what you do to one side you must do to the other)x = -35Therefore, the sum of 20 and -35 is -15.
The two numbers that solve this problem are 5 and 15. The sum of 5 and 15 is equal to 20, and 15 is indeed 3 times 5.
