the answer is B

Simplifying

         3(4x + -1) + -7x = 17

Reorder the terms:

        3(-1 + 4x) + -7x = 17 (-1 * 3 + 4x * 3) + -7x = 17 (-3 + 12x) + -7x = 17

Combine like terms:

       12x + -7x = 5x -3 + 5x = 17

Solving

       -3 + 5x = 17

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation.

       -3 + 3 + 5x = 17 + 3

Combine like terms:

       -3 + 3 = 0 0 + 5x = 17 + 3 5x = 17 + 3

Combine like terms:

       17 + 3 = 20 5x = 20

Divide each side by '5'. x = 4 Simplifying x = 4

Maximum slope for hand-propelled wheelchair ramps should be 1" of rising to every 12" of length (4.8-degree angle; 8.3% grade).

Maximum slope for power chairs should be 1.5" rise to 12" length (7.1-degree angle; 12.5% grade).

Minimum width should be 36" (inside rails) - (48" is ideal).

100 Hz x .30 m = 30 m/s

just kidding :D

cause only me wears Nike 

yeah 

ya LOL
