-18 - 6k = 6 + 18k
help me please

k=-1

Step-by-step explanation:

Given:

-18 -6k=6 + 18k

Add 6k on both sides

-18 - 6k + 6k=6 + 18k + 6k

-18=6+24k

Subtract 6 on both sides

-18 - 6=6 + 24k - 6

-24=24k

Divide 24 on both sides

-24 / 24=24k /24

k=-1

ask the math teacher she or he would know lol.

step-by-step explanation:

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
