4 x 15 x 25 = 1,500.
When X = 4, 15X = 15 * X = 15 * 4 = 60
If x - (-15) = 11 then x = -4.
3/5 x 5/12 x 4/15 = 3 x 5 x 4/5 x 12 x 15= 5 x (3 x 4)/5 x 12 x 15= 1/15
[ (x - 4) / 15 ] / [(2x + 13) / 15] = (x - 4) / (2x + 13)
4 x 15 + 9 = 69
3.75 0.25 = 25/100 = 1/4 15 x 1/4 = 15/4 = 3.75
4x-15=1 15+1=16, 16/4=x=4 x=4
Expressed as a formula, this is equal to (15 + 4)/x.
x2 - 19x + 60 = x2 - 15x - 4x + 60 = x(x - 15) - 4(x - 15) = (x - 15)(x - 4)
4, 6 and 15 or 46 and 15 cos 4,6 and 15 LCM is 360 (4 x 6 x 15)
(7 - x/4) = 15 x/4 = 7 - 15 x/4 = -8 x = -32 Verification: 7 - ( -32/4) = 7 - (-8) = 7 + 8 = 15
