Question

The solution of - t/18 ≥ 10 is t ≤ -180
True or false?

Answer 1

t <= -180 True.

Explanation:

-t/18 >= 10

Multiply both sides by 18

-t >= 180

Divide both sides by -1 :-

t <= -180 (NOTE: when we divide by a negative the inequality sign is flipped)

Answer 2

True

Explanation:

given -
`(t)/(18)` ≥ 10 (multiply both sides by 18 )

- t ≥ 180 ( multiply both sides by - 1)

Remembering to reverse the symbol as a consequence of multiplying by a negative quantity, hence

t ≤ - 180
