well, a WHOLE is 1, which we can split in many fractions, say 5/5, 10/10 or 999/999 and so on.
we know 1/5 of the jar is chocolate chip, and there's the rest, well, the Whole jar in 5ths have to be 5/5, if we take away 1/5 from 5/5, the "rest" is 5/5 - 1/5 = 4/5.
now, we also know that 1/2 of the "rest" is peanut butter, or namely that 1/2 of 4/5 is peanut butter, how much will that be? let's divide 4/5 by 2
![\cfrac{4}{5}\div 2\implies \cfrac{4}{5}\div \cfrac{2}{1}\implies \cfrac{4}{5}\cdot \cfrac{1}{2}\implies \cfrac{4}{10}\implies \cfrac{2}{5}](https://tex.z-dn.net/?f=%5Ccfrac%7B4%7D%7B5%7D%5Cdiv%202%5Cimplies%20%5Ccfrac%7B4%7D%7B5%7D%5Cdiv%20%5Ccfrac%7B2%7D%7B1%7D%5Cimplies%20%5Ccfrac%7B4%7D%7B5%7D%5Ccdot%20%5Ccfrac%7B1%7D%7B2%7D%5Cimplies%20%5Ccfrac%7B4%7D%7B10%7D%5Cimplies%20%5Ccfrac%7B2%7D%7B5%7D)
Answer:
According to the data given Neighborhood A has a larger family size on Average by 7/9s. Neighborhood A had a more consistent family size than Neighborhood B which is part of what caused it too have a higher average family size.
Step-by-step explanation:
Neighborhood A- 44 total / 9 families 4 and 8/9 per family
Neighborhood B- 37 total / 9 families 4 and 1/9 per family
Hey there!
First, we'll need to isolate the y variable, meaning that we'll need all of the y's on one side. To do this, we'll need to subtract 8x from both sides. This leaves us with 2y = -8x - 10.
Second, we'll need to get y all by itself, without the 2. To do this, we'll need to divide both sides by 2. This leaves us with y = -4x - 5.
Therefore, your answer is the first option, or the darkest blue box.
Hope this helps!! :)
