75% of 200 = 50; 20% of 160 = 128

Step-by-step explanation:

200 (0.75) = 150

200 - 150 = 50

-6x - 7 is greater than or equal to - 19. Please guide me through the steps of this... I will give brainliest
3241004551 [841]

Answer:

x ≤ 2

Step-by-step explanation:

                                       -6x - 7 ≥ -19

Add 7 to both sides:            -6x ≥ -12

Divide both sides by 6:          -x ≥ -2

Divide both sides by -1:            x ≤ 2

When you divide by a negative, you have to switch the sign around (hence why I chose to do this in separate steps, so it's clearer)
