First, solve the given system of linear equations.

Second, multiply the first equation by 4 (which was an arbitrary choice).  Add your result to the 2nd equation.

You should now have the following:

First equation:  No change:             <span>2x + 7y = 1

Second equation:  4(</span><span>-3x – 4y = 5) = -12x -16y = 20

Solve this new system of linear equations.  Do you (or do you not) obtain the same solution as your earlier one?</span>

Murrr4er [49]
Given the table below which lists the masses and volumes of several pieces of the same type of metal.<span>

From the table the ratio of the mass to the volume of the metal of mass 34.932 is 34.932 / 4.1 = 8.52
</span><span>the ratio of the mass to the volume of the metal of mass 47.712 is 47.712 / 5.6 = 8.52
</span><span>the ratio of the mass to the volume of the metal of mass 61.344 is 61.344 / 7.2 = 8.52
</span><span><span>the ratio of the mass to the volume of the metal of mass 99.684 is 99.684 / 11.7 = 8.52

</span>MASS (grams)            VOLUME (cubic cm.)
34.932                               4.1
47.712                              5.6
61.344                              7.2
99.684                              11.7</span>

Since the ratio of the various masses to the volume of the metals is the same, so there is a relationship between the mass and the volume of the piece of metal.

If the volume of a piece of metal is 15.3 cubic cm, then the mass of the metal is given by 15.3 * 8.52 = 130.356 grams.

What is the measure of the missing angle? Round answer to nearest whole number.
LenKa [72]

Answer:

you know that you have the Opposite side and the Adjacent side. therefore you would use Tangent (T= O/A)

because you are finding the angle you would go Tan^-1(12÷20) =31°

it is 12÷20 because O/A and the 12 is the opposite side therefore It would be O and 20 is the adjacent side therefore equaling 20 so O/A = 12/20

Your answer is 31°
