<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)
Answer:
Step-by-step explanation:
if you know that the perimeter is 20,
then you have to divide by 4 to get the length of one side
20/4=5.
Draw the diagonal and write in it's length as x.
Use Pythagorean formula
Then know that a2+b2=c2
and use the two side lengths as a and b.
This gives you the equation
5^2+5^2=x^2.
Do the calculations and solve the equation.
25+25=x^2
50=x^2
√50=x.
Therefore x=√50 where x equals the length of the diagonal.
