To work through a problem like this, first find how many ordered pairs you’re given. In this case, it’s 5.
The answer will always match the amount of ordered pairs given, IF no two x-values are the same. For this scenario, each x-value is unique, so you will have an answer with exactly 5 values. This rules out A and D.
From there, just take the x-value of each ordered pair, list ‘em in order, and you get your answer.
B is the correct answer
Answer:
Step-by-step explanation:
Sara sold $3350 in ads,
Kenny sold $1368, and
Leila sold $456
(a)
total sale=3350+1368+456=$5174
Sara's fraction=3350/5174=0.6475
Kenny's fraction=1368/5174=0.2644
Leila's fraction=456/5174=0.0881
(b)
total bonus=$150
Sara's bonus=150*0.6475=$97.12
Kenny's bonus=150*0.2644=$39.66
Leila's bonus=150*0.0881=$13.22
Answer:
1) -15/32
2) 2/15
3) -203.5
4) -3/2 = -1.5
5) 10/3 = 3 1/3
Step-by-step explanation:
For 1, you just multiply the numerators and denominators together (3 by 5, 4 by 8) and then because it is negative, add the negative sign.
For 2, you multiply again, but because there are 2 negative signs, it becomes positive.
For 3, you divide 81.4 by 0.4, you could also divide 814 by 4.
For 4, you keep change flip, so the equation would become -9/4 (-2 1/4=-9/4) and 3/2 would become 2/3. The equation would be (-9/4 * 2/3). Then, you would get -18/12 which is -3/2.
For 5, you just multiply 4/3 by 5/2 which is 20/6 and because 2 negatives, it becomes positive.
the correct answer is - 1/2
