Oh ok , I G u e s s it is solved already.
The answer
<span>the amount of gold per cubic meter can be found by the ratio
0.78 g /1 </span><span>.5 cubic meters = 0.52 g / cubic meter,
proof
it was said </span><span>the amount of gold per cubic meter (Density)</span>
Hmm dont really know this one let me think againf
Solve the following system of equations by using the substitution method.
2x – 3y = -1
y = x – 1
<span>
(4, 3)|
</span>Solve the following system of equations by using the substitution method.
3y – 2x = 11
y + 2x = 9
<span>
Inconsistent|
</span>Solve the following system of equations by using the elimination method.
-2x + 9y = -13
6x – 3y = 15
