Help due Monday......

Step-by-step explanation:

5) 2.4×10^-5 / 4.5×10^-11

2.4×10^-5= 0.0000244.5×10^-11= 0.000000000045

=0.000024/0.000000000045

=24/1 × 1,000,000/45

=24,000,000/45

=533,333.33°

=5.33333°×10^5

2x + 3 = 5x - 22x - 5x = - 2 - 3-3x = -5x = -5/-3x = 1.66°6x + 4 = 6x + 46x - 6x = 4 - 40x = 02 (2x + 3) = 8x - 24x + 6 = 8x - 24x - 8x = -2 - 6-4x = -8x = -8/-4x = 2-3x + 2 = -3x + 5-3x + 3x = 5 - 20x = 3

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

Step-by-step explanation:

3x - 2y = –9

3x−2y+2y=−9+2y

3x=2y−9/3x^3

=2y−9/3

x=2/3y−3

4x + 3y = 22

4x+3y+−3y=22+−3y

4x=−3y+22

4x4

=−3y+22/4

x=−3/4y+11/2
