First, we separate all instances of t by subtracting J from both sides:

F = J + Jrt
F - J = Jrt

Then, we separate the t by dividing both sides by Jr:

$\frac{f - j}{jr} = t$
Therefore, t is equal to (F - J) ÷ Jr

A pair of dice is rolled, and the number that appears uppermost on each die is observed. Refer to this experiment and find the p

Reptile [31]

The probability for each die is 1/6
so you multiply 1/6 by 1/6
to get 1/36 so the probability of getting any given event is
1/36

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.
