It is so very simple and quick to get the answer, especially since, if you need it, you can use the calculator that comes with your computer. But since you are obviously not able to do so, the answer is 60.
It is: 12+18+30 = 60
12+14+18 = 44
18
That one is easy it is 18 and 12
(18 + 12) ÷ 6 = 5
18 + 12 = 30
6 and 12 hope it helps
18. 1+8=9 9x2=18
18 - 12 - 14 = -8
It is: 12+18+30 = 60
12+14+18 = 44
18
Smaller number = x Larger number = 2x x+2x=18. 3x=18 x=6 The numbers are 6 and 12.
That one is easy it is 18 and 12
18 + 12 = 30 18 - 12 = 6
18 is the only number (other than 0) that is twice the sum of its digits.
(18 + 12) ÷ 6 = 5
