a ≥ –5 and a ≤ 5

a ≤ –5 and a ≥ 5

a ≤ –5 or a ≥ 5

Which expression is equivalent to |a|≤5 ?

a ≥ –5 or a ≤ 5

a ≥ –5 and a ≤ 5

a ≤ –5 and a ≥ 5

a ≤ –5 or a ≥ 5Which expression is equivalent to |a|≤5 ?

a ≥ –5 or a ≤ 5

a ≥ –5 and a ≤ 5

a ≤ –5 and a ≥ 5

a ≤ –5 or a ≥ 5Which expression is equivalent to |a|≤5 ?

a ≥ –5 or a ≤ 5

a ≥ –5 and a ≤ 5

a ≤ –5 and a ≥ 5

a ≤ –5 or a ≥ 5

The answer would be a>-5 or a< 5

Step-by-step explanation:

I hope this helps, let me know if i'm incorrect

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
