22 + 8 - 10 = 20 Therefore, the number he is thinking of is 22.
Adding a % and a whole number: Example: 50% of 20 + 8 = 50% x 20 + 8 = 0.50 x 20 + 8 = 10 + 8 = 18
Since your number line starts at 20, add 20 to your figures and you will come up with the same answer. 21 - 8 = 41 - 28 = 13
22 Double it, add two, double it, add two, etc.
first you add 1 by 5 and get 6 then .add 6 by 2 and get 8 .and add 8 by 3 and get 11.add 11 by 4 get 15.add 15 by 5 get 20 its simple just keep adding each number by 1,2,3,4,5 and if the pattern continues keep going
You add 20

First add 8 and 9 to get 17. Then divide 340 by 17 to get 20. Then times 20 by 8 to find the number of girls or times 20 by 9 to get the number of boys. Number of girls: 160 Number of boys: 180

Add four to the previous number. 4, 8, 12, 16, 20, 24 and so on.
If you add 27 and 8, the answer is 35. 7 plus 8 is 15 and add it to 20, the answer is 35.
