Instead of subtracting 6 from 12 then dividing they added 6 to 12 & ended up with 18. 18 by 2 is 9.
Answer:
We got less than 2 1/2 ft
Step-by-step explanation:
We need to add up all the snow on the three days
Monday = 15 inches
Tuesday = 4 1/2 inches
Wednesday =6 3/4 inches
------------
25 + 1/2 + 3/4 inches
Getting a common denominator
25 + 2/4+3/4
25 + 5/4 inches
25 + 1 + 1/4 inches
26 1/4 inches of snow
2 1/2 ft
1 ft = 12 inches
2 ft = 24 inches
1/2 ft = 6 inches
2 1/2 ft = 24+ 6 inches
= 30 inches
26 1/4 inches < 30 inches
We got less than 2 1/2 ft

Step-by-step explanation:
Given equation is:
6.2 ÷ (2x+1) = 2 1/3 ÷4
Applying the division operation
![\frac{6.2}{2x+1} = 2\frac{1}{3} * \frac{1}{4}\\\frac{6.2}{2x+1} = \frac{7}{3}*\frac{1}{4}\\\frac{6.2}{2x+1} =\frac{7}{12}\\](https://tex.z-dn.net/?f=%5Cfrac%7B6.2%7D%7B2x%2B1%7D%20%3D%202%5Cfrac%7B1%7D%7B3%7D%20%2A%20%5Cfrac%7B1%7D%7B4%7D%5C%5C%5Cfrac%7B6.2%7D%7B2x%2B1%7D%20%3D%20%5Cfrac%7B7%7D%7B3%7D%2A%5Cfrac%7B1%7D%7B4%7D%5C%5C%5Cfrac%7B6.2%7D%7B2x%2B1%7D%20%3D%5Cfrac%7B7%7D%7B12%7D%5C%5C)
Cross multiplication
![6.2(12) = 7(2x+1)\\14x+7 = 74.4\\14x = 74.4-7\\14x = 67.4](https://tex.z-dn.net/?f=6.2%2812%29%20%3D%207%282x%2B1%29%5C%5C14x%2B7%20%3D%2074.4%5C%5C14x%20%3D%2074.4-7%5C%5C14x%20%3D%2067.4)
Dividing both sides by 14
![\frac{14x}{14} = \frac{67.4}{14}\\x = 4.8142857....](https://tex.z-dn.net/?f=%5Cfrac%7B14x%7D%7B14%7D%20%3D%20%5Cfrac%7B67.4%7D%7B14%7D%5C%5Cx%20%3D%204.8142857....)
Rounding off to nearest hundredth
![x = 4.82](https://tex.z-dn.net/?f=x%20%3D%204.82)
