Answers:

1)In this first question we have to clear
x from the following equation:


x+15.09=-2.57


x=-15.09-2.57


x=-17.66

2)Here we have to find the value of
x in the following inequality:


-6>-30-4x


4x-6>-30


4x>-30+6


4x>-24


x>-(24)/(6)

Then:


x>-6

3)Here we have to find the value of
t in the inequality:


-22t>66

Note that -22 is a negative number and is dividing
t, this number goes to the other side of inequality dividing, and the direction of the inequality must change:


t<-(66)/(22)

Finally:


t<-3
