Let x be the number and so it is: 3x-18
18 = XVIII
18 - (25%) = 13.5
It leaves 18 balloons.
It is: 18-3D
18-d3
18 - 3n
Let x be the number and so it is: 3x-18
32 - 2x < 18
When 18 is decreased by (-27), the result is 45.
It would be: 18 -x
Cut in half, decreased by 50%.
18 = XVIII
If you mean 6:20 pm, then you could write it in 24-hour-time which would make it 18:20
