HELP ASAP!!

Solve the inequality for t:

`0.1 - 2t \geqslant 0.7`
A.
`t \leqslant - 0.4`
B.

`t \geqslant - 0.3`
C.

`t \leqslant - 0.3`
D.

`t \geqslant - 0.4`

Answer 1

Let's begin by listing out the information given to us:

0.1 - 2t ≥ 0.7

Subtract "0.1" from both sides, we have:

0.1 - 0.1 - 2t ≥ 0.7 - 0.1

-2t ≥ 0.6

Divide both sides by "-2", we have:

t ≥ -0.3
