1/6x = 2.....multiply both sides by the reciprocal 6/1
(6/1)(1/6)x = 2(6/1)
1x or just x = 12
There is no real planet that is 1/10 the distance Uranus is from the sun, however the planetoid (smaller planet), Vesta is 1/9 the distance Uranus is from the sun.
It should be A. You would keep the 5, and the exponent should be 4+8, which is 12.
32-x=0; with x equaling the amount descended or -32.
