Please explain.
This is what i understand from you're "sentence":
5 and 6 are the same as 10 and 12 because both are integers and both are positive.
Answer:
10 x 10 x 10 x 10
Step-by-step explanation:
10^4 is equivalent to 10 x 10 x 10 x 10
So it should be to the nearest tenth or hundredth ?
Let the numbers be x = 5x+18
3(5x+18) + 4x= 16
15x+ 54+ 4x= 16
19x = 16-54
X=-38/19
X= -2
5x+18= 5 × -2+18 = 8
This is esay to do when you realize the the speed of mowing is addtive. This is if John mows at 1 lawn / (2/3) hour and Gerge mows at 1 lawn / 1hour, the total speed of mowing is:
1 / (2/3) + 1 = 3/2 + 1 = 5/2
=> 5/2 of lawn per hour
Now, the time is calcualted as the amount of lawn divided by the speed:
1 lawn / (5/2 lawn/hour) = 2/5 hour.
Answer: 2/5 of an hour.
