Enter your answer as a decimal in the box.



Solve for x.

−6>−30−4x



Enter your answer, as an inequality, in the box.


Solve for t.

−22t>66



Enter your answer, as an inequality, in the box.

Answer 1

X+15.09= - 2.57

X=17.66

-6> -30-4x

X<15

-22t>66

t < -3

Answer 2

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`
