Answer:
of the distance
Step-by-step explanation:
We know that a ferry traveled 
of the distance between two ports in 
hours.
In order to calculate what fraction of the distance between the two ports can the ferry travel in one hour we can do the following reasoning :
The rate of the ferry is the same at any time.
The ferry will travel of the distance in hours.
If we divide each fraction by 3 ⇒
and 
We do this to obtain a ''1'' in the numerator of the second fraction (the hours fraction). Now, we can say that :
The ferry will travel 
of the distance in 
hours.
Finally, we multiply each fraction by 7 (in order to obtain the distance for 1 hour) ⇒
and 
We found out that the ferry will travel of the distance in 1 hour.
Answer:
b squared + 20b+ 100
Step-by-step explanation:
multiply Using the FOIL method
first inner outer last
so
b times b = b squared
10 times b equals 10b
b times 10 equals 10b (again)
10 times 10 equals 100
add up all the answers to get the final answer
b squared + 20b+ 100
Answer:
$7
Step-by-step explanation:
You can see that it "rises" 700 and "runs" 100, that means that there is a slope of 700/100. If you simplify that, it turn out to be a slope of 7. Meaning that each ticket costs $7. Hope this helps, let me know if you need a better explanation!
Answer:
(2,1,0)
Step-by-step explanation:
3x+3y+6z=9
3(2)+3(1)+6(0)=9
6+3+0=9
6+3=9
9=9
x+3y+2z=5
x(2)+3(1)+2(0)=5
2+3+0=5
2+3=5
5=5
3x+12y+12z=18
3(2)+12(1)+12(0)=18
6+12+0=18
6+12=18
18=18
if you add up all the marbles and then put it as the denominator then put 2 on top. divide. then do the same except this time take 1 minus the amount of total marbles . put it as the denominator and then 2 on top. divide. next take both numbers and make them a fraction. turn to simplest form. ithink
