Question 35430
The diameter of the planet Uranius is 10 times larger than mercuries. If the sum of both planets is 54,867 km.What is the diameter of each one.

Let diameter of mercury by x.
Then diameter of Uranus is 10x
EQUATION:
x+10x=54867
11x=54867
x=4987.91 km (diameter of Mercury)
10x=49879.10 km (diameter of Uranus
