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

X +5 divided 4x^2+14x-9

masya89 [10]

Answer:

x =(14-√340)/8=(7-√ 85 )/4= -0.555

x =(14+√340)/8=(7+√ 85 )/4= 4.055

Step-by-step explanation:

step 1 :

(22x2 - 14x) - 9 = 0

Step 2 :2.1 Factoring 4x2-14x-9

The first term is, 4x2 its coefficient is 4 .

The middle term is, -14x its coefficient is -14 .

The last term, "the constant", is -9
