The chance that any given bulb is on is equal to 1/2. The chance that all twenty bulbs are on at the same time is
You can answer this question in numerous ways but one simple way is by multiplying fractions.
<span>2/3 of 24 is also 2/3 of 24/1 </span>
<span>To get the answer, you must multiply 2/3 by 24/1 </span>
<span>To do this, you multiply the numerator (the top number) by the other numerator. That is, 2 x 24 . The answer is 48. </span>
<span>Then, multiply the denominators (the bottom numbers) by each other. That is, 3 x 1. The answer is 3. </span>
<span>The answer is 48/3. But you must continue simplifying. </span>
<span>What is 48 divided by 3? 16. </span>
<span>If you do not understand it that way, think of it in a simpler way. </span>
<span>Say there are 24 slices of pieces. </span>
<span>What is one third of those 24 slices? </span>
<span>24 divided by 3 = 8. </span>
<span>Now you want TWO thirds. So all you do is multiply 8 by 2. </span>
<span>That gives you 16.

w=7.5
Step-by-step explanation:
area of triangle is 6x5=30/2= 15 and then you divide 15 which 7.5
44-11=33
33+11=44
The answer is 33
Given,
The linear pair of the equation is,
![\begin{gathered} 3x+y=-7 \\ 4x-y=14 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%203x%2By%3D-7%20%5C%5C%204x-y%3D14%20%5Cend%7Bgathered%7D)
Required
The solution of the linear equation.
Taking the equation first as,
![\begin{gathered} 3x+y=-7 \\ y=-7-3x \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%203x%2By%3D-7%20%5C%5C%20y%3D-7-3x%20%5Cend%7Bgathered%7D)
Substituting the value of y in second equation then,
![\begin{gathered} 4x-y=14 \\ 4x+7+3x=14 \\ 7x+7=14 \\ 7x=7 \\ x=1 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%204x-y%3D14%20%5C%5C%204x%2B7%2B3x%3D14%20%5C%5C%207x%2B7%3D14%20%5C%5C%207x%3D7%20%5C%5C%20x%3D1%20%5Cend%7Bgathered%7D)
Substituting the value of x in first equation then,
![\begin{gathered} 3x+y=-7 \\ 3(1)+y=-7 \\ y=-7-3 \\ y=-10 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%203x%2By%3D-7%20%5C%5C%203%281%29%2By%3D-7%20%5C%5C%20y%3D-7-3%20%5C%5C%20y%3D-10%20%5Cend%7Bgathered%7D)
Hence, the solution of the system is (1, -10).
