I am taking an astronomy class because I am interested in it and wanted to know more. I love all I am learning unfortunately my math skills are holding me back from getting all that I can out of this class. I realize this might not be the toughest math problem but can someone explain help me out with these two questions? The first question asks for R in terms of d1. I'm not sure what this means.(adsbygoogle = window.adsbygoogle || []).push({});

The Sun is 1,047 times more massive than Jupiter. Call the mass of the Sun m1 and that of Jupiter m2. The ratio m1/m2 is then 1,047. If the first equation is divided through by m2, we find that d2 = 1,047 d1, The Sun moves around the center of mass for the Sun-Jupiter system in an orbit about one thousand times smaller than Jupiter’s orbit. This motion for the Sun is small but not insignificant.

m1 d1 = m2 d2

d1 + d2 = R

Using the second equation, what is R in terms of d1 given the value of d2 above? R=_____d1

If R, the total distance between the Sun and Jupiter, is 7.783 x 108 km (5.2 AU), what is d1 in km? d1= _____km
