Answer:
D) 9:20 am
Step-by-step explanation:
Train A's route = 20 mins
Train B's route = 80 mins
80 ÷ 20 = 4
Therefore, Train B's route is 4 times the length of Train A's route.
Therefore, the time Train A and B will leave the station at the same time will be the first time Train B leaves after 8am.
1 hour = 60 minutes
8am + 80 minutes = 8am + 1 hr + 20 minutes = 9:20 am
Answer:
Step-by-step explanation:
143=5x+13(being corresponding angles)
143-13=5x
130/5=x
26=x
Answer:
The system has infinitely many solutions
Step-by-step explanation:
we have
----> equation A
----> equation B
Multiply by -2 both sides equation A

----> equation C
Compare equation B and equation C
The equations are identical (is the same line)
therefore
The system has infinitely many solutions
Is a consistent dependent system
3.9 · 0.5 + 4 5/6 ÷ 3 3/7
1.95 + 4 5/6 ÷ 3 3/7 multiplication left ot right
1.95 + 29/6 ÷ 24/7 convert to improper fraction
1.95 + 29/6 · 7/24 divide by fraction same as multiplication by reciprocal
1.95 + 203/144 multiply
1.95 + 1.40 (and a teensy bit more)
3.35
