10,20,30,40,50,60,70
7,14,21,28,35,42,49,56,63,70
So the LCM is 70
<span>The perimeter of a rectangle is the distance around the outside of the rectangle. A rectangle has four sides with opposite sides being congruent. The formula for finding the perimeter is Side A + Side B + Side A + Side B. This could also be stated as 2*Side A + 2*Side B or 2*(Side A + Side B)

Answer:
![\large\boxed{\large\boxed{slope=-2/5}}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7B%5Clarge%5Cboxed%7Bslope%3D-2%2F5%7D%7D)
Explanation:
The problem is: <em>given the points (19,−2) and (−11,10) find the slope of the line that joins them.</em>
The <em>slope </em>of a line is the change in the y-coordinate over the change of the x-coordinate:
- slope = rise / run = Δy / Δx
Thus:
![slope=[10-(-2)]/[-11-19]\\\\slope=12/(-30)\\\\slope=-12/30](https://tex.z-dn.net/?f=slope%3D%5B10-%28-2%29%5D%2F%5B-11-19%5D%5C%5C%5C%5Cslope%3D12%2F%28-30%29%5C%5C%5C%5Cslope%3D-12%2F30)
Simplify, dividing both numerator and denominator by 6:

His dog ate 1/2 of his collection, this means that there are only 33 left. If I multiply 33x2, I will get 66. Therefore, Fred started with 66 cards.
(If you’re not counting the cards he purchased, then Fred would have 59 cards.)
Put all the white balls in one box and the red ball in the other so you have a 50% chance of winning if you put 1 red ball and a white now you have a 25% chance cause you have a 50% chance in choosing the right box then you have to chose the right ball which would be 50%
