It is: 14/15 divided by 13/9 = 42/65
Density = (mass) divided by (volume) = (42) divided by (7) = 6 grams per cm3 . Next time, it'll be a lot easier if you just have your teacher contact us directly.
42/6 + 2*3 = 7+6 = 13
42.7647
g/5 -13 = 42 (add 13 to both sides) g/5 = 55 (multiply both sides by 5) g = 275
The way to approach this is to write a algebraic equation: 13 - (x/7) = 6 Times both sides by 7 which gives: 13 - x = 42 Take away 13 on both sides which gives: -x = 29 x = -29 Now to check it 13 - - 29 = 42 (two negatives make a positive 42 divided by 7 = 6
1 kilogram = 1,000 grams 42 kilograms = 42,000 grams
