16 bags are $8. However, you need more than 16 bags; you need 84.
So the first thing you do is divide 84 by 16 which is 5.25. This means that if 16 bags are $8, then you need to multiply the price and quantity by 5.25 to work out how much it is for 84 bags:
$8 = 16 bags
Multiply by 5.25:
$8 * 5.25 = 16 bags * 5.25
$42 = 84 bags
Therefore, it’ll cost $42 to buy 84 bags.
Find the angle of 1, which would be the same as angle of 5 (alternate interior angles applicable to parallel lines).
38+<1=180 degrees (<1 just represents angle one)
<1=180-38
<1=142 degrees
Therefore, the angle of 5 is 142 degrees as well.
Hope I helped :)
Multiply q and 2
Multiply q and 1
The q just gets copied along.
The answer is q
q
2*q evaluates to 2q
2*q+2 evaluates to 2q+2
2 + 9 = 11
The answer is 11+2q
At the beginning you have 10 balls, 5 of which are red. So, the chance of picking a red ball with the first pick is
![\dfrac{5}{10}=\dfrac{1}{2}](https://tex.z-dn.net/?f=%5Cdfrac%7B5%7D%7B10%7D%3D%5Cdfrac%7B1%7D%7B2%7D)
When it comes to the second pick, you have 9 balls (because you didn't replace the first red ball), 3 of which are blue. So, you pick a blue ball with the second pick with probability
![\dfrac{3}{9}=\dfrac{1}{3}](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B9%7D%3D%5Cdfrac%7B1%7D%7B3%7D)
The two events will occur one after the other with the product of the probabilities:
![\dfrac{1}{2}\cdot\dfrac{1}{3}=\dfrac{1}{6}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D%5Ccdot%5Cdfrac%7B1%7D%7B3%7D%3D%5Cdfrac%7B1%7D%7B6%7D)
