Answer:
Well, assuming that these are cubes labeled 1-6, there is a 1/12 chance of the sum equaling 2, since they would both have to land on 1
Step-by-step explanation:
Let the speed for the first 12 mi be x mi/h, the speed for 18 mi was (x+4) mi/h
thus given that
time=distance/speed
the average time will be:
3=(12+18)/(x+x+4)
3=30/(2x+4)
solving for x we get
3(2x+4)=30
6x+6=30
6x=24
x=4 mi/hr
Answer: 12 mi/hr
Answer:







Step-by-step explanation:
Thanks!!!!
1+2+3= 6 (even)
2+3+4= 9 (odd)
it can be both
The answer is x is less than or equal to 3. the first answer choice
