an equation to determine how many games, n, Pedro
played at the carnival.

c=4n+9/ Pedro played 12 games at the carnival.

Step-by-step explanation:

After writing the equation( c= 4n+9) you would place 57 in the c variable and solve for n.

57=4n+9

48=4n

12=n

if im not mistaking its

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
