<h3>Given</h3>
- 5 movies and 2 video games rent for $26
- 3 movies and 8 video games rent for $53
<h3>Find</h3>
<h3>Solution</h3>
Let m and v represent the rental cost of a movie and a video game, respectively. The given information can be expressed in two equations:
... 5m +2v = 26
... 3m +8v = 53
Using Cramer's rule, we can find the solution to be
... m = (2·53 -8·26)/(2·3-8·5) = -102/-34 = 3
... v = (26·3-53·5)/-34 = 5.50
The rental cost for each movie is $3; for each video game is $5.50.
_____
The Vedic math variation of Cramer's Rule tells you the solution to
is ...
- x=(bf-ec)/(bd-ea)
- y=(cd-fa)/(bd-ea)
I would choose to have a higher initial rate of zombies with a slower growth rate because (although it would be difficult in the beginning) i would have more time to prepare for the zombies.
Answer:
2x^2 + 2x +3
I think that this is correct
Answer:
<u>x=0</u>
all you have to do it plug the diffrent answers into as x and see which one works out, in this case 0 works on both side to get it equale

1st half life: 195/2 = 97.5 g
2nd half life: 97.5/2 = 48.75 g
3rd half life: 48.7/2 = 24.375 g
4th half life: 24.375/2 = 12.1875 g
5th half life: 12.1875/2 = 6.09375 g
or you can do
195(2)^(-5) = 6.09375
** rounded to nearest gram = 6 g
