Answer:


Step-by-step explanation:

6A) Death Valley is located below sea level.  It says it is -282 feet.  This means that it is below 0 and sea level is marked at 0.

6B) 5280 + 282 = 5562 ft higher

6C)  The closer you get to the ocean the closer you are to 0.  If you were in the water floating on top you would be at 0.

13) all 3 are 28

The parenthesis have to stay.  This is how we know to distrubute the 2 across the problem.

How do you solve the following system of equations by eliminating the y-values? I've already solved it by eliminating the x-valu
AlexFokin [52]

Step-by-step explanation:

The coefficients of the y terms are -3 and 2.  The least common multiple of 3 and 2 is 6.  So multiply the first equation by 2 and the second equation by 3, so that the y terms have a coefficient of 6.

4x − 6y = 42

-18x + 6y = 21

The signs are opposite, so add the equations together.

-14x = 63

x = -9/2
