Which equation has infinitely many solutions? a 3x−2=2−3x b x+3x+6=6+4x c 2x+7x−5=−9x+5 d 4x−5x+3=−5x+4x−3

The table below shows the approximate masses of a dust particle and a grain of pollen. dust particle 0.000000778 g grain of pollen 0.00000000155 g the mass of a dust particle can be estimated and written in the form a × 10^b, where a = 8 and b = the mass of a grain of pollen can be estimated and written in the form a × 10^b, where a = 2 and b = based on the estimates, the mass of a dust particle is approximately blank times larger than the mass of a grain of pollen.
