To find this answer is this way:
Assuming that one rational number is positive, and one number is negative. The only way you can tell if it will positive, negative, or zero is by answering the question it self...
So (for example):
-2.2222 + 2.2222 = 0 <--- zero is if both numbers are the same (except for its symbols)
-3.251 + 0.258 < 0 <--- negative is if the positive is less then the negative number...
-0.2858 + 3.254 > 0 <--- positive is if the negative is less than the positive number...
Answer:
B
Step-by-step explanation:
Average rooms cleaned per housekeeper day: The average number of rooms cleaned per housekeeper day is performance ratio that gives an idea of how many rooms each housekeeper cleaned.
Average rooms cleaned per housekeeper day =
2x + 3y = -21
2x = -21 - 3y
x = -10.5 - 3/2y
-10x + 2y = 20
-10(-10.5 - 3/2y) + 2y = 20
105 + 15y + 2y = 20
105 + 17y = 20
17y = -85
y = -5
2x + 3y = -21
2x + 3(-5) = -21
2x - 15 = -21
2x = -6
x = -3
Therefore, the coordinates are (-3, -5).
