Answer:

202.9 cm^3

Step-by-step explanation:

Mass is 712.04 grams

Density is 3.51 grams/cm^3

Volume = (712.04 g)/(3.51 grams/cm^3) = 202.9 cm^3

To solve this problem, there is a very simple trick, once you see it. The first step is to subtract the second equation from the first equation. This gives:

6x + 6y = 60

Multiply by 5/3 to get 10x + 10y

10x + 10y = 60 * 5/3

10x + 10y = 100

The line through (1, 7) and (-6,7) in point-slope form

Natasha2012 [34]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ 1 &,& 7~) 
% (c,d)
&&(~ -6 &,& 7~)
\end{array}
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{7-7}{-6-1}\implies \cfrac{0}{-7}\implies 0
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-7=0(x-1)$
