12/1.25=9.6 cents
9.6 cents
3/12 simplifies to 1/4.
Since 1/2 of an hour is one whole hour, you must multiply 1/4 by two. This gives you 2/4, or 1/2.
So the train travels 1/2 of the distance between the two cities in one hour.
12x6 is 72 (mental math)
Then add three zeros to 72.
12000x6= 72000
Answer:
D = -7
Step-by-step explanation:
The two angles are adjacent on a straight line so they are supplementary. Thus 8x+5+13x-14=180
21x-9=180
21x=189
x=9
