Solve 7x - 2y = -3 14x + y = 14 (1 point) in the below system, solve for y in the first equation. x - 3y = -6 2x - 7y = 10 (1 point) what is the value of y in the solution to the following system of equations? 5x - 3y = -11 2x - 6y = -14 (1 point) use the substitution method to solve the following system of equations. 3x + 5y = 3 x + 2y = 0 (1 point)

0if x and y vary inversely and y=6 as x=7, what is the constant of variation?

Nthe opening scene of the movie raiders of the lost ark, indiana jones replaces a golden statue with a bag of sand. the platform on which the statue is placed is designed to detect the mass of the statue. if the bag of sand has a different mass than the statue, then a mechanism triggers and destruction ensues. the density of gold is about 20\text{ g/cm}^320 g/cm 3 20, space, g, slash, c, m, start superscript, 3, end superscript. the density of sand can be estimated at 2.5\text{ g/cm}^32.5 g/cm 3 2, point, 5, space, g, slash, c, m, start superscript, 3, end superscript. the gold statue can be modeled as a cylinder with height 25\text{ cm}25 cm25, space, c, m and radius 8\text{ cm}8 cm8, space, c, m. in terms of \piπpi, what is the mass of sand indiana jones needs to avoid triggering the mechanism?
