Answer:
<h2>
x = 19</h2><h2>
</h2>
Step-by-step explanation:
|<----------------- 71 ----------------------->|
E-----------------------F---------------------G
2x + 13 20
find: x
EF + FG = DG
2x + 13 + 20 = 71
2x = 71 - 20 - 13
x = 38 / 2
x = 19
I dont know if you know this, but there are 3 different 3's. So how can we figure out the question if we don't know which one is underlined?
Hello,
1 liter of water in normal conditions has a volume of 1dm^3=(1dm)^3=(10 cm)^3=10^3 cm^3=1000 cm^3
Write the equation of the first train: x = 12t
Write the equation of the second train: y = -20t+72, assuming the train one is at the origins when t = 0.
Now solve the equation: 12t=-20t+72,
32t = 72, then t = 2.25 hours. The two train meet after 2.25 hours.
Now the equation of the <span>pigeon is like this: x = 48t.
</span>Then for t = 2.25, we get

The Hyde has flown 108 km when the trains meet.</span>
