Answer: 20 hours
Step-by-step explanation: We want to round our answer to the nearest hour, we know that the rocket can travel 200 miles per 1 minute, but we want to know first how many miles the rocket can travel per 60 minutes or 1 hour.
To find how many miles the rocket can travel at 60 minutes or 1 hour, simply multiply 200 x 60. 200 x 60 = 12,000 miles per hour.
Now, we want to find how many hours it would take for the rocket to travel from the earth to the moon.
Simply divide 239,000 by 12,000 to get the amount of hours it would take to reach the moon. 239,000/12,000 = about 20 hours.
So, it would take the rocket ship 20 hours to reach the moon from the earth.
Consecutive integers are 1 apart
they are
x,x+1,x+2
add to 15
x+x+1+x+2=15
3x+3=15
minus 3 both sides
3x=12
divide both sides by 3
x=4
x+1=5
x+2=6
they are 4,5,6
Answer:
21000 meters
Step-by-step explanation:
100R + 300B
100(30) + 300(60)
3000 + 18000 = 21000
X + y = 12
x - y = 4
From the second equation we can see that x = 4 + y
We can plug this into the first one and get:
4 + y + y = 12
4 + 2y = 12
2y = 12-4
2y = 8
y = 4
And then we can plug that into “x” and get that x = 4 + 4, or x=8
I hope this helps you
5-2x=15
5-15=2x
2x= -10
x=-5
