David bought a silver ring at a jewelry store. he finds that the density of the ring is 10.5 grams per cubic centimeter and its volume is 2 cubic centimeters. what is the mass of the ring? a.21 g b.42 g c.57 g d.78 g

If I'm not mistaken you just multiple since it's 10.5 grams per cubic centi. since it's 2 cubic centis, the answer is A) 21

128/3reason being 5 and 1/3 = 16/316/3 • 2/3 = 32/31 and 1/3 = 4/3 32/3 • 4/3 this will equal 128/3

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
