Let S, M, L represent the shortest, mid-length, and longest sides, respectively. You are given three bits of information.
.. S +M +L = 14.5 cm
.. L = 2S
.. L = 6.2 cm
You can use an equation something like this to find the middle-length side.
.. (6.2 cm)/2 +M +6.2 cm = 14.5 cm
.. M +9.3 cm = 14.5 cm . . . . . . . . . . . . . constant terms collected
.. M = 5.2 cm . . . . . . . . . . . . . . . . . . . . . subtract 9.3 cm
Now, you know the side lengths are 3.1 cm, 5.2 cm, 6.2 cm.

You have not offered any choices for "which equation," so take your pick of those used here.
Answer:
15
Step-by-step explanation:

Subtract 1 from both sides:

Multiply both sides by 5:

Divide both sides by 2:

2 +4 +3 = 9 total balls
if they pick a white one first there would be 8 balls left
there are 2 blue ones so probability would be 2/8 which reduces to 1/4
Answer:
Hi! You didn't really provide a shape which would allow me to explain this much more easily but it's okay. The way to find the translation is very simple. Find the plotted points of the original figure, and make sure you label them and their coordinates so you know where they are. Then, to graph the translation, using those original coordinates, add one to all of the X's, and subtract four from all of the Y's. That will allow you to see what your prime picture will look like.
If this is still confusing, let me know and I'll be happy to further explain.

Answer:
19/21 hours, about 54 minutes 17 seconds
Step-by-step explanation:
The time is found from ...
time = distance/speed
time = (95 mi)/(105 mi/h) = 95/105 h = 19/21 h
The trains will meet after 19/21 hours, about 54 minutes, 17 seconds.
