Answer:
The number 0 is the only number in the group that would make this true.
First things first, distance = speed x time
So let's have "t" represent the time by both trains.
The first train shall be Train A and the other becoming Train B, so now we have Train A going 80t miles and Train B going 100t miles.
If two trains head toward each other, they will have traveled a total of 252 miles. The faster train will have traveled further (Train B), so the meeting point will be closer to the slower train's starting point (Train A).
So now we do 80t + 100t = 252
Which becomes 180t = 252
And by diving 252 by 180, you'll get that t is 1.4
This would mean they would meet at one hour and 24 minutes.
Answer:
23.5 is the answer
Step-by-step explanation:
X10 =235 so x=235÷10 = 23.5
Answer:
y +9 = 15(x -2)
Step-by-step explanation:
The point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . for slope m and point (h, k)
Here, you are given m=15 and (h, k) = (2, -9). Putting these values into the form gives the equation ...
y +9 = 15(x -2)
