On Monday Simon's class filled 3 2/5 boxes with books to donate to charity. On Wednesday the class filled 4 2/5 more boxes with
TiliK225 [7]

Simon class donated 7\frac{4}{5} \text{ or } 8 boxes of books

<h3><u>Solution:</u></h3>

Given that,

On Monday Simon's class filled 3\frac{2}{5} boxes with books to donate

On Wednesday the class filled 4\frac{2}{5} more boxes with books

To find: total number of boxes of books donated

Total number of boxes of books donated = boxes filled in monday + boxes filled in wednesday

From given statement,

Boxes of books filled in monday = 3\frac{2}{5} = \frac{5 \times 3 +2}{5} = \frac{17}{5}

Boxes of books filled in wednesday = 4\frac{2}{5} = \frac{5 \times 4+2}{5} = \frac{22}{5}

Therefore,

Total number of boxes of books donated = \frac{17}{5} + \frac{22}{5}

\rightarrow \frac{17}{5} + \frac{22}{5} = \frac{17+22}{5} = \frac{39}{5} = 7\frac{4}{5} = 7.8\\\\\rightarrow 7.8 \approx 8

Thus simon class donated 7\frac{4}{5} \text{ or } 8 boxes of books

Answer:

x =(14-√340)/8=(7-√ 85 )/4= -0.555

                       or

x =(14+√340)/8=(7+√ 85 )/4= 4.055

Step-by-step explanation:

step  1  :

 (22x2 -  14x) -  9  = 0
