Answer:

#z<40#

Explanation:

To isolate for #z#, multiply by the reciprocal of the coefficient, which is #2#:

#\frac{1}{2}x<20#

#2\cdot\frac{1}{2}z<20\cdot 2#

Simplify both sides

#z<40#

This means that any value of #z# less than #40# will satisfy this inequality.

Answer:

#z<40#

Explanation:

#1/2 z <20#
Multiply both sides by #color(red)(2)#
#2(1/2 z) < (2)(20)#
#cancel2/cancel2 z < 40#
# z < 40#
