15=30-3x 15-30=3x -15=3x -15/3=x -5=x
30% of 15 = 0.3 x 15 = .45
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
3 x 5 = 15 2 x 3 x 5 = 30 2 x 3 x 5 = 30, the LCM
1 x 30, 2 x 15, 3 x 10, 5 x 6, 6 x 5, 10 x 3, 15 x 2, 30 x 1.
Assuming a value of 30 for x, then 15 x 30 = 450.
30 2 x 15 = 30 30 2 x 15 = 30
1 x 30, 2 x 15, 3 x 10, 5 x 6, 6 x 5, 10 x 3, 15 x 2, 30 x 1.
15=30-3x 15-30=3x -15=3x -15/3=x -5=x
15% = 0.150.15 x 200 = 30
30
x times 30% = 15 x = 15/.3 = 50
The greatest common factor of 15 and 30 is 15.15 x 1 = 1515 x 2 = 30
30% of 15 = 0.3 x 15 = .45
If you mean: x+y = 30 and the value of y is 15 then the value of x is also 15
1 x 30 2 x 15 3 x 10 5 x 6
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
