Answer:
1.3125 gallons would have been wasted in 7 days
Step-by-step explanation:
mathematically, there are 0.0625 gallons in a measuring cup
So within the time frame, 0.0625 of liquid was lost
The time frame is 8 hours difference
The number of hours in 7 days will be;
7 * 24 = 168 hours
0.0625 gal in 8 hours
x gal in 168 hours
x * 8 = 168 * 0.0625
8x = 10.5
x = 10.5/8
x = 1.3125 gallons
Answer:
w = ![-\frac{9}{8}](https://tex.z-dn.net/?f=-%5Cfrac%7B9%7D%7B8%7D)
Step-by-step explanation:
The question is ![4w-4+2(5w+8)=-2(w+3)](https://tex.z-dn.net/?f=4w-4%2B2%285w%2B8%29%3D-2%28w%2B3%29)
We can first use distributive property to simplify, the distributive property is ![a(b+c)=ab+ac](https://tex.z-dn.net/?f=a%28b%2Bc%29%3Dab%2Bac)
Thus we have:
![4w-4+2(5w+8)=-2(w+3)\\4w-4+10w+16=-2w-6](https://tex.z-dn.net/?f=4w-4%2B2%285w%2B8%29%3D-2%28w%2B3%29%5C%5C4w-4%2B10w%2B16%3D-2w-6)
<em>Now we combine like terms and simplify to get the final answer for w</em><em>.</em>
![4w-4+10w+16=-2w-6\\14w+12=-2w-6\\14w+2w=-6-12\\16w=-18\\w=\frac{-18}{16}\\w=-\frac{9}{8}](https://tex.z-dn.net/?f=4w-4%2B10w%2B16%3D-2w-6%5C%5C14w%2B12%3D-2w-6%5C%5C14w%2B2w%3D-6-12%5C%5C16w%3D-18%5C%5Cw%3D%5Cfrac%7B-18%7D%7B16%7D%5C%5Cw%3D-%5Cfrac%7B9%7D%7B8%7D)
Thus, w = ![-\frac{9}{8}](https://tex.z-dn.net/?f=-%5Cfrac%7B9%7D%7B8%7D)
