X-2(x+10)=12 need work shown

Mathematics
1 answer:
Eva8 [605]3 years ago
5 0

Answer:

x=-32

Step-by-step explanation:

expand -2(x+10): -2x-20

x-2x -20=12

add similar elements: x-2x=-x

x-20=12

add 20 to both sides

-x-20+20=12+20

simplify

-x=32  

divide both sides by -1

x=-32

Carmen is considering joining one of the two movie clubs. Movie Galore charges a monthly membership fee of $10, plus $0.50 per m
lakkis [162]
25 movies.

So basically you start and end at 1 month so,

Galore Cost =

Galore Per Movie = 
0.5 x 25 = 12.5 + 10 = $22,5

Cinephile Cost = 
$15
Cinephile Per Movie = 
0.25 x 25 = 6.25 + 15 = 21.25
