Answer:
Step-by-step explanation:
1) 5(2x + 3) + 3(x -4) = 25
Use distributive property
5*2x + 5 *3 + 3*x - 3*4 = 25
10x + 15 + 3x - 12 = 25
Add like terms
10x + 3x +15 - 12 = 25
13x + 3 = 25
Subtract 3 form both sides
13x = 25 - 3
13x = 22
x = 22/13
x =
2) Breadth = b m
Length = 5b - 4
Perimeter of rectangle = 40 m
2*(length + breadth) = 40 { Plug in the values of breadth & length}
2* (5b - 4 + b) = 40
2 * ( 6b - 4 ) = 40
2*6b - 2 *4 = 40
12b - 8 = 40 { add 8 to both sides}
12b - 8 + 8 = 40 + 8
12b = 48 { divide both sides by 12}
12b/12 = 48/12
b = 4 m
Breadth = 4m
Length = 5*4 - 4 = 20 - 4 = 16 m
It takes 16 movie rentals for both options to be the same price
<u>Solution:</u>
Given that, A local DVD rental machine rents movies out to customers for $5.75 per movie.
A digital movie company allows you to rent movies for $3.25 but requires a membership fee of $40.
We have to find how many movie rentals will it take for both options to be the same price?
Now, let the number of movies rented be "n"
Then, according to the given information,
Hence, it takes 16 movies to be the same price for both options.
