The Tama monorail runs for 18 hours every day.
29*2.4-36.5= 33.1 hrs before the freight train cought up.
6÷2(1+2) = 6÷2*(1+2) = 6÷2*3 = 3*3 = 9.
This is just like the other problem. The coefficient infront of the b which is "2" is your constant of proportionality. It makes the relationship between the number of bulbs and flowers signaling that for every flower there has to be 2 bulbs.
Answer:
Step-by-step explanation:
A. (b - 10)(b + 10) = 180
-100 = 180
= 280
b = 
b = 2
Your A is correct.
B. 2
- 10 = c
c = 6.733200531 = 6.73 Try rounding to 3 significant figures.
C. 2
+ 10 = d
d = 26.73320053 = 26.7
You are correct in all 3 answers. Perhaps you should try rounding to 3 significant figures for your c and d values.
I hope this helps!! ^-^
