Answer:
D
Step-by-step explanation:
It is a trinomial with a degree of 3.
This is the correct answer on the exam.
First, we have to find the rate:
500/50
100/10
10/1
10 cents a pitch:
129 * 10 = 1290
It will cost $12.90
Let n be Fritzs' car speed, and n+12 be the speed of the train. Then:
1/2 (n)=1/3 (n+12)
2n+24=3n
n=24 mph
n+12=36 mph
Fritz travels 12 miles to work.
30 min @24mph=12 miles
20 min @36mph=12 miles
