Answer:
A. (-7 -2)
Step-by-step explanation:
You can eliminate y by multiplying the first equation by 7 and subtracting 6 times the second equation:
7(-3x +6y) -6(5x +7y) = 7(9) -6(-49)
-21x +42y -30x -42y = 63 +294 . . . . eliminate parentheses
-51x = 357 . . . . . . . . collect terms
x = -7 . . . . . . . divide by -51. This matches answer choice A.

Answer:
60%
Step-by-step explanation:
A percent is technically just a fraction over 100.
To get that here, we simply divide the part (which is 1560 people) by the whole (which is 2600 people) and then multiply that by 100:
(1560 / 2600) * 100 = 0.6 * 100 = 60/100
Thus, we know that the percent is 60%.
