Answer:
It annually drops by 20%
Step-by-step explanation:
30,000 multiplied by 20% is 6000. Subtract 6000 from 30,000 and you get 24,000. 24,000 multiplied by 20% is 4,800. Subtract 4,800 from 24,000 and you get 19,200. Etc.
Answer:
No solution 0≠3
Step-by-step explanation:
simplify parenthesis:
4x+4x+3=8x+6
combine like terms:
8x+3=8x+6
subtract three from both sides
8x=8x+3
subtract 8x from both sides
0≠3
This equation has no solution
i hope this helps u, pls give brainliest i only need one more then i level up and a thx, leave a comment if i am wrong
Answer: $16
with the base being $6, you can write the equation 6 + .5x = y
“x” is represented by the number of songs downloaded, so we can replace x with 20
y is the total amount of money
6 + .5(20) = y
now, all you have to do is solve
6 + 10 = y
16 = y
