Answer:

x>2

Step-by-step explanation:

-1>-2(x-4)-5(4x-7)

opening brackets

-1>-2x+8-20x+35

-1>-2x-20x+8+35

-1>-22x+43

-1-43>-22x

-44>-22x

by canceling the sign of minus we change the sign of inequality

44<22x

x>2

i hope it will help you

How to set the answer up
Korolek [52]

Let s and g represents the numbers of suits and gowns produced.

The number of zippers used is 2s+g.

The number of buttons used is 5s+8g.

In order to use all of the available zippers and buttons, we must have ...

  • 2s + g = 171
  • 5s + 8g = 576

Cramer's rule tells you the solution to the system

  • ax +by = c
  • dx +ey = f

Is given by

  • x = (bf-ey)/(bd-ea)
  • y = (cd-fa)/(bd-ea)

Using this rule on the equations for zippers and buttons, we have

... s = (1·576 -8·171)/(1·5 -8·2) = -792/-11 = 72

... g = (171·5 -2·576)/-11 = -297/-11 = 27

72 suits and 27 gowns can be made from available zippers and buttons.
