x = 10

Step-by-step explanation:

50 = (6x - 10)      rewrite it

50 =  6x - 10

+ 10        + 10       add 10 to both sides

60 =  6x               you're left with 60 and 6x

60/6 = 6x/6         divide both sides by 6 to get x by itself

10 = x                    the answer is whatever you're left with after dividing

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
