Step-by-step explanation:

5) 2.4×10^-5 / 4.5×10^-11

  • 2.4×10^-5= 0.000024
  • 4.5×10^-11= 0.000000000045

=0.000024/0.000000000045

=24/1 × 1,000,000/45

=24,000,000/45

=533,333.33°

=5.33333°×10^5

  1. 2x + 3 = 5x - 2

  • 2x - 5x = - 2 - 3
  • -3x = -5
  • x = -5/-3
  • x = 1.66°

  1. 6x + 4 = 6x + 4
  • 6x - 6x = 4 - 4
  • 0x = 0

  1. 2 (2x + 3) = 8x - 2
  • 4x + 6 = 8x - 2
  • 4x - 8x = -2 - 6
  • -4x = -8
  • x = -8/-4
  • x = 2

  1. -3x + 2 = -3x + 5
  • -3x + 3x = 5 - 2
  • 0x = 3

Letter be has no solution because it is broken down as "0x = 0"
