Answer 1

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"
