We can simplify it by combining like terms
We get -7x -3x = -10x and -10x+8x = -2x
then we get -2x + 2 = -8
-2x = -10
x = 5
Step-by-step explanation:
It takes Mercury approximately 58 days, 15 h, and 30 min to complete a full rotation.. We are going to write the time not in days, hours and minutes, but only hours. This means that we have to write 58 days as hours and 30 minutes as hours. 1 day is 24 hours, so 58 days are 58*24=(50+8)*(20+4)=50*20+50*4+8*20+8*4=1,000+200+160+32 =1,200+192=1,392 (hours) 60 minutes are 1 hour, so 30 minutes are 0.5 hours. Thus 58 days, 15 h, and 30 min are (1,392+15+0.5) hours = 1,407.5 hours Answer: 1,407.5 hours

Answer:
The waiter earns 15 dollars an hour
Step-by-step explanation:
250- 125 is 125 so the worker earns 125 over a time span of 10 hours so we need to divide 125 by 9 which then we get 15.625 . Correct me if I'm wrong it says this is a Highschool leveled question and I'm not in Highschool.
