For this case we convert the mixed numbers to fractions:
Dwight:
Mike:
It is observed, that in fact, Mike takes more time to travel the road.
We subtract to know how much more time it takes Mike:
So, Mike takes 
hours more than Dwight to walk the road.
Answer:
Mike takeshours longer than Dwight to walk the road.
Well for two positive numbers subtracted to equal a negative number, the first number must have a value that is less than the second number. (Ex. 3-4= -1) In this case, you can conclude that x is less than y! (x<y)
Answer:
wouldn't that just be -35?
Step-by-step explanation:
you just have to do -29-6
X= first number
x+1= second number
2x+1=275
2x=274
x+274
x=137 first number
137+1=138 second number
Answer:
612 feet
Step-by-step explanation:
LA is located at 330 feet ABOVE SEA LEVEL
Death Valley is located 282 feet BELOW SEA LEVEL
We let the sea level be at 0 (consider a number line).
So,
LA would be at +330 feet
and
Death Valley would be at -282 feet
The elevation change between the two would be the difference:
330 - (-282) = 330 + 282 = 612 feet
The difference in elevation = 612 feet
