Answer:
Elimination
Step-by-step explanation:
A system of equations is 2 or more equations for which the same x,y solution exists. We can solve the system in three ways: elimination, substitution, or graphing. Elimination is the best method when we have standard form equations and x values with opposite coefficients. This is so because the x variable will eliminate easily and allow us to solve for y.
Answer:
Twenty two over nine.
Step-by-step explanation:
The bar over the 4 means that 4 is recurring .44444......... It goes on with out bounds and is equal to 4/9.
So 2.4 = 2 4/9
= 22/9.
There appear to be 2 treasures marked with X on the map. One is at (15°S, 120°W); the other is at (45°S, 120°E). The first of these is both northernmost and westernmost. The second of these is on its own island. Since it is the only treasure that is not the northernmost, it is also the closest to the northernmost.
- (15°S, 120°W)
- (15°S, 120°W)
- (45°S, 120°E)
- (45°S, 120°E)

<em>Comment on the map</em>
There appear to be additional features marked with a double "circle". We cannot tell if these are mountains, or are supposed to represent treasure locations. They are generally at spots that would require interpolation of the coordinates, so we suspect they are not relevant to the problem. Both "land masses" are completely surrounded by "water", so we aren't sure which is to be considered "its own island". A legend could be helpful.
294 chairs divided by 14 chairs means there are 21 tables. Since there’s actually only 12 chairs at each table, then 12 times 21 tables = 252 chairs left
Answer: 52:3
