Answer: B

Step-by-step explanation:

Equation A:

15x - 45 = 75x + 75

=> -120 = 60x

=> x = -2

Equation B:

15x - 45 = 15x + 75

=> 0 = 15

<em>No Solutions</em>

<em />

Equation C:

45x - 45 = -15x + 75

=> 60x = 120

=> x = 2

Equation D:

-45x - 45 = -75x + 75

=> 30x = 120

=> x = 4

Step-by-step explanation:

1) A number <em>m</em> is at least four

<em>m ≥ 4  ['at least' = ≥ symbol]</em>

<em />

2) 4x  ≤ 20x; x=2

4(2) ≤ 20(2)

8 ≤ 40

[Im not sure if this is a solution or and inequality :/ ]

3)  x < 5

--> On the line, draw the number 0, and the number five. 'x < 5' also means 'x is less that five.' So, draw a dot over the line before 5, and make an arrow going to the left of the page,
