<h3>Given</h3>
  • 5 movies and 2 video games rent for $26
  • 3 movies and 8 video games rent for $53
<h3>Find</h3>
  • the rental cost of each
<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

  • ax+by=c
  • dx+ey=f

is ...

  • x=(bf-ec)/(bd-ea)
  • y=(cd-fa)/(bd-ea)

18+ (-30)<br> Integers help plssss
Neko [114]

Answer: -12

Step-by-step explanation: To solve this problem, we can first start by rewriting the problem. When we add a negative, that's exactly the same thing as subtracting so we can make the problem easier to understand.

18 + (-30) → 18 - 30

To find the answer to this problem, let's first find out how many jumps it get's to 0 from 18. It would take 18 jumps and there is 12 jumps left over. Then, we would subtract 12 from 0 and we would get -12 as our answer. Therefore, 18 + (-30) = -12.

Step-by-step explanation:

the angles of a triangle all add up to 180

thus, we can combine every term given and set them equal to 180 and solve for x

9x + 72 = 180 \\ 180 - 72 = 108 \\ 108 \div 9 = 12
