Train A arrives at central station on the hour and every 12 minutes. Train B arrives on the hour and every 15 minutes. When do both trains arrive at thesame time?
I believe that both trains would arrive at the same time on the hour (D).
Hope this helped :)
Answer:
600 students attend the school.
Step-by-step explanation:
495-7=488
488/4=122
488+122= 600

Step-by-step explanation:
The midpoint will be -> (3, 2)
We get this from plugging in our numbers (file 2) and solving. You get (6/2, 4/2) which results in (3, 2).

Answer:
x=-1
Step-by-step explanation:
hello :
3x+9-7x=2(x+6)
3x+9-7x=2x+12
3x-2x-7x=12-9
-6x = 6
x=6/-6 = -1
<h2>Steps</h2>
- Standard Form Equation: f(x) = ax² + bx + c
So firstly, since (0,5) is one of our values we can plug it into the standard form equation to solve for the c variable (since 0 will cancel out the a and b variable):

Now we know that the value of c is 5. Next, plug in (-1,12) into the standard form equation and simplify (remember to also plug in 5 for the c variable):

Next, plug (2,15) into the standard form equation and simplify:

Now, with our last two simplified equations we will create a system of equations:

Now, I will be using the elimination method with this system. With the system, add up the equations together and you will get:

From here, we can solve for the a variable. With it, just divide both sides by 3:

Now that we know the value of a, plug it into either equation to solve for the b variable:

<h2>Answer</h2>
Putting all of our obtained values together, your final answer is:
