3x
3x + 9 = -6 3x = -15 x= -5
As an expression it is: 3x+5
3x + 5 < 12
If: 3x+9 = 24 Then: 3x = 24-9 So: 3x = 15 => x = 15/3 The number is 5
3x

3(3x - 5y)(3x + 5y)
3x + 9 = -6 3x = -15 x= -5
It can be: 3x+4
3x + 1
4x=10+3x or 10+3x=4x
Three times as much force is needed to give the same acceleration to the 1500-kilogram car compared to the 500-kilogram car. This is because the force required is directly proportional to the mass of the object being accelerated according to Newton's second law of motion, F = ma.
3x + 8

As an expression it is: 3x+5
3x + 5 < 12
