One month Boris rented 2 movies and 5 video games for a total of $33. The next month he rented 8 movies and 3 video games for a total of $30. Find the rental cost of each movie and you each video game.
1 answer:
M=cost per movie v=cost per video game 2m+5v=33 8m+3v=30 use elimination eliminate movies mutliply first equation by -4 and add to 2nd first equation becomes -8m-20v=-132 add the 2 equations -8m-20v=-132 <u>8m+3v=30 +</u> 0m-17v=-102 -17v=-102 divide both sides by -17 v=6 subsiutute back 2m+5v=33 2m+5(6)=33 2m+30=33 minus 30 both sides 2m=3 divide 2 m=1.5 rental cost per movie is $1.50 rental cost per video game is $6

Answer:
1. 142. 2. adjacent angles.
Step-by-step explanation:
1. because it is less then 180, that would be flat, and it is bigger then 132.
2. because they are adjacent to each other.
I think its letter D because x + 2y fits with the equation and there for -3
This equation in numbers: (-8x)^6 • (4x)^2 (262144•x^6) • (16x^2) 4,194,304x^8
D is wrong. It’s an exponential function so every year the number of stores it opens grows. Which means there can’t be one number for each year in terms of amount of new stores.
(7 and 7/16) is the simplest form.
