Answer:

Yes, all three of them are proportional

Step-by-step explanation:

First, let's simplify them all the way:

10/45 = 2/9

20/90 = 2/9

6/27 = 2/9

All three of these ratios simplified down to their simplest form are 2/9, meaning that they are all proportional.

4(-4x - 3) > 36 with the steps
Sergeu [11.5K]

Answer:

x < -3

Step-by-step explanation:

Divide both sides by 4. Since 4 is positive, the inequality direction remains the same.

−4x−3> 36/4

​Divide 36 by 4 to get 9.

−4x−3>9

Add 3 to both sides.

−4x>9+3

Add 9 and 3 to get 12.

−4x>12

Divide both sides by −4. Since −4 is negative, the inequality direction is changed.

x< 12/-4

​ Divide 12 by −4 to get −3.

x < -3
