5x-5=75-25x , how do you do the steps of this?

Add 5 to both sides

5x = 75 - 25x + 5

Simplify 75 - 25x + 5 to -25x + 80

5x = -25x + 80

Add 25x to both sides

5x + 25x = 80

Simplify 5x + 25x to 30x

30x = 80

Divide both sides by 30

x = 80/30

Simplify 80/30 to 8/3

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
