It's moving day, and Lydia has packed her books into large and small boxes. The large boxes hold 35 books, and the small ones ho

Virty [35]

The number of large boxes is 4 and the number of small boxes is 14.

<u><em>Explanation</em></u>

Suppose, the number of large boxes is $x$ and the number of small boxes is $y$

As, the total number of boxes is 18, so the first equation is....

$x+y= 18 .......................................(1)$

The large boxes hold 35 books, and the small ones hold 20 books and the total number of books is 420. So the second equation will be .....

$35x+20y=420................................(2)$

Now solving equation (1) for $y$ itself , we will get....

$y= 18-x$

We will plug this $y= 18-x$ into equation (2). So.....

$35x+20(18-x)=420\\ \\ 35x+360-20x=420\\ \\ 15x= 420-360\\ \\ 15x=60\\ \\ x= \frac{60}{15}=4$

Now plugging this $x=4$ into the equation $y= 18-x$ .......

$y= 18-4= 14$

Thus, the number of large boxes is 4 and the number of small boxes is 14.

$\mathsf{2^6 = 2\times2\times2\times2\times2\times2}\\\mathsf{2\times2\times2\times2\times2\times2}\\\mathsf{2\times2=4}\\\mathsf{4\times4\times4}\\\mathsf{4\times4=16}\\\large\mathsf{16\times4=64}\\\mathsf{2^6 = \bf{64}}$

$\mathsf{4^4=4\times4\times4\times4}\\\mathsf{4\times4\times4\times4}\\\mathsf{4\times4=16}\\\mathsf{16\times16}\\\mathsf{16\times16=256}\\\mathsf{4^4=\bf{256}}$
