18 and 25
To write this algebraically: 2x+18>25 and solve: 2x>25-18 x>7/2 Therefore x (a number) must be greater than 7/2.
You can't, a SUM is the amount obtained as a result of adding numbers (18+7=25)18x7 is asking you to MULTIPLY the two numbers. This is call the PRODUCT of the two numbers (18*7 = 126).
The sum of 16 and 18 is 34.
The sum of -18 and 39 is 21.
The sum of 24, 15, 18, 18, 11, 25, 27, and 22 is 160. The addition process involves combining the individual values by adding them together. In this case, adding the numbers sequentially results in a total sum of 160.
20, is the sum of 18 and 2.
The mean = The sum of all the values ÷ The number of values. 18 + 15 + 22 + 18 + 25 + 19 + 23 = 140 : Number of values = 7 Mean = 140 ÷ 7 = 20
The sum of 18, 6 and 6 is 30. That is, 18 + 6 + 6 = 30.
18 + 12 = 30
