Answer:
No
Step-by-step explanation:
2X + 12=13x - 2x + 5
2X + 12= 11x+5
2x-11x = 5-12
-9x = -7
X = 7/9
so the answer is NO
Answer:
The correct answer is (4) a ratio variable
Step-by-step explanation:
Nominal, ordinal, interval, or ratio data are the four fundamental levels of measurement scales that are used to capture data.
Nominal scales are used for labeling variables, without any quantitative value.
Ordinal the order of the values is what is significant, but the differences between each one is not really known.
Interval we know both, the order and the exact differences between the values
Ratio they have the order, the exact value between units, and have an absolute zero
In this case, the concentration of DDT (C14H9Cl5), in milligrams per liter is a RATIO, because it has order, the exact value between units, and have an absolute zero
So if 2 people take 9 hours to paint the room and you want to know how long it will take if 3 people were painting first you will have to find the slope, or the rate of change, to do this you have to divide 9/2.
9/2= 4.5
So it take 4.5 hours for one person to paint the room.
Therefore if there where three people painting it would be 3 x 4.5= 13 hours and 30 minutes.
The time it would take to paint the room would increase.
Hi there!
First let's multiply the fraction 1/4 x 3/3. This will give us all of the same denominators. Now, we have 6 3/12, 5 5/12, and 6 1/12. Since the lowest number is 5, we know that 5 5/12 is the smallest value. Then, we see that we have two 6's left. Since 3/12 is bigger than 1/12, we know that 6 1/12 comes after 5 5/12. Lastly, 6 3/12 is the greatest.
ORDER:
5 - 5/12, 6 - 1/12, 6 - 3/12
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
If you add 900 and 900, you get 1800, but there has to be 14 in between both, so if you add 7 to one and subtract 7 to the other, one would be 893, and the other would be 907
