Answer:
8. Identify the common denominator; express each fraction using that denominator; combine the numerators of those rewritten fractions and express the result over the common denominator. Factor out any common factors from numerator and denominator in your result. (It's exactly the same set of instructions that apply for completely numerical fractions.)
9. As with numerical fractions, multiply the numerator by the inverse of the denominator; cancel common factors from numerator and denominator.
10. The method often recommended is to multiply the equation by a common denominator to eliminate the fractions. Then solve in the usual way. Check all answers. If one of the answers makes your multiplier (common denominator) be zero, it is extraneous. (10a cannot have extraneous solutions; 10b might)
Step-by-step explanation:
For a couple of these, it is helpful to remember that (a-b) = -(b-a).
<h3>8d.</h3>
___
<h3>9b.</h3>
___
<h3>10b.</h3>
Neither solution makes any denominator be zero, so both are good solutions.

Answer:
220g/cm³
Step-by-step explanation:
Given parameters:
Mass of the weight = 220000g
Volume = 1000cm³
Unknown:
Density of weight = ?
Solution:
Density is the mass per unit volume of a substance.
Mass is the amount of matter in a substance.
Volume is the amount of space a substance occupies
Density =
Input the parameters and solve
Density = = 220g/cm³
