Question

0.5x+4<0.9x-1 the solution is {x|x blank, blank}

Answer 1

sorry korie i got this wrong the last time
if u subtract 0.5x from both sides you get
4 < 0.4x -1 (i got 0.5x last time!!)
now add 1 to both sides:
0.4x > 5
x > 5 / 0.4
x > 12.5
i think the
answer in the form you require is {x|x 12.5, infinity}
