Not really. Lets say you have 19.8% of x ingredient, 20.7% of y ingredient, 30.6% of m ingredient ad 28.9% of k ingredient. For this medicine, the values would be rounded of to 20%, 21%, 31% and 29%....which adds up to 101%. So by rounding of to he nearest whole percent, you get a total percentage of more than 100%. This would be seen in the other medicines used in 'the table'. The fact that the total percentage for each one would add up to different values each time and not be constant makes the comparison invalid because the conditions being compared would be different.
You have failed to provide the actual table, so I tried to do my best to come up with example figures to help you answer the question using the figures you have.

Answer:
lower left
Step-by-step explanation:
We notice that the answer choices have only the first equation changed. The equivalent of the first equation must have the same ratios of coefficients.
x-coefficient : y-coefficient : constant
= 2 : 1 : -15 . . . . . in the given equation
2 : -2 : 30 = 1 : -1 : 15 . . . upper left — not the same
-4 : -2 : -15 = 4 : 2 : 15 . . . upper right — not the same
-4 : -2 : 30 = 2 : 1 : -15 . . . lower left — same as the given equation
-4 : 1 : 30 = 4 : -1 : -30 . . . lower right — not the same
Answer:
4x - 16
Step-by-step explanation:
X can be any value (I made it 20)
5.5(2)+ 1 - (1.5(2) +17)
11 + 1 - 20
12 -20
-8
4(2) - 16
8 - 16
-8
You better say thanks (from a grade 9 academic student)
I started at (-2, 0) but you can start at any point on the graph that goes through the corner of the square (if that makes sense) like a point on the graph. From one point to the next, you go down one and one to the right, therefore the slope is a -1
This is a unit rate question. We can solve this in chronological order of steps:
Step 1: Write out the beginning for the first unit rate.
Faith completed 60 burpees in 5 minutes last week.
Step 2: Since 60 burpees were completed in 5 minutes, we can divide 60 by 5 to find how many burpees were completed in 1 minute.
60 divided by 5 equals 12.
5 divided by 5 equals 1.
Our fraction for how many burpees Faith did in a minute last week is 12/1. This reduces to 12, meaning that Faith did 12 burpees last week.
Step 3: Find the unit rate for this week.
Faith completed 78 burpees in 6 minutes this week. Because of this, we can divide 78 by 6 to find how many burpees Faith completed this week.
78 divided by 6 equals 13.
6 divided by 6 equals 1.
Our final fraction for how many completed burpees Faith did this week is 13/1, which reduces to 13. Therefore, Faith completed 13 burpees per minute this week.
Your final answer: In terms of separate values, Faith completed 12 burpees per minute last week and 13 burpees per minute this week. If you need help, let me know and I will gladly assist you.
