Answer:
30 miles
Step-by-step explanation:
2.5 h
12 miles per hour
12x2.5=30
(400,000 + 230,000) / 16.5 = 630,000 / 16.5 = 38181.8....rounds to 38182 units
Currently there are 28 children playing. Until a moment ago, 4 of those 28 werent there. To find out how many there were a moment ago, we have to exclude those 4 kids that just came — or subtract the number of kids that just came from the number of kids currently playing.
28-4=24
We can check: 24+4=28
The answer to that question is x=1
Answer:
the first one
Step-by-step explanation:
Think of it this way. If it needs to be greater than -11, that means there is some kind of restraint. that would be in this situation, its under a square root. if you plug in -11, it should equal 0, so it has to be x+11 under square root. The second one wouldn't work since that would make it square root of -22 and thats imaginary, same thing with all the others, when you plug in -11, the last 3 would come negative. the first one is the only one that cancels the negative and gives you 0
