At total of 2 feet of snow falls over three days on the first day 1/6 of the snow falls on the second day 7/12 of the snow falls

ioda

Answer:

$Day\ 3 = 1\frac{3}{12}$

Step-by-step explanation:

Given

$Total = 2ft$

$Day\ 1 = \frac{1}{6}$

$Day\ 2 = \frac{7}{12}$

Required

Determine the amount of snow on day 3

This can be calculated using:

$Day\ 1 + Day\ 2 + Day\ 3 = Total$

Substitute values for the known parameters

$\frac{1}{6} + \frac{7}{12} + Day\ 3 = 2$

Collect Like Terms

$Day\ 3 = 2 - \frac{1}{6} - \frac{7}{12}$

Take LCM

$Day\ 3 = \frac{24 - 2 - 7}{12}$

$Day\ 3 = \frac{15}{12}$

Express as mixed number

$Day\ 3 = 1\frac{3}{12}$

4s² + <u>14</u>s + 10
4s² + 4s + 10s + 10
2s(2s) + 2s(2) + 5(2s) + 5(2)
2s(2s + 2) + 5(2s + 2)
(2s + 5)(2s + 2)

4s² + <u>22</u>s + 10
4s² + 20s + 2s + 10
2s(2s) + 2s(10) + 1(2s) + 1(10)
2s(2s + 10) + 1(2s + 10)
(2s + 1)(2s + 10)

It could be equal to 14 or 22.
