The mass of a block of a stone is 2,000 kg. If the block has a volume of 0.5 m3, What is its density? Remember, density is mass per unit of volume. A. 4,000 kg/m3. B. 1,000 kg/m3

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
