Answer:
3x+18
Step-by-step explanation:
since 3 is outside the bracket you need to multiply 3 by both x and 6. so 3 multiply x is 3x and 3 multiply 6 is 18, hence 3x+18
Answer:
The fraction will increase by 100%
Step-by-step explanation:
Say the fraction is x/y. The question is telling us to decrease x by 20% (i.e. 0.8x) and to decrease y by 60% (i.e. 0.4y):
![= \frac{0.8x}{0.4y}\\= 2 (\frac {x}{y})](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B0.8x%7D%7B0.4y%7D%5C%5C%3D%202%20%28%5Cfrac%20%7Bx%7D%7By%7D%29)
You can see that by applying these changes, the new fraction is actually double the old fraction (i.e. will increase by 100%).
Answer:
y = 0.75x + 1.95
Step-by-step explanation:
It is given that the variables:
y stands for total cost
x for the amount of songs.
It is also given that each song costs $0.75 to download, and that there is a standard flat-fee of $1.95 (per month).
Set the equation:
total cost for the month = cost per song * amount of song + flat fee subscription
or
y = 0.75x + 1.95

1/6 * 3/2 = 1/4
5^2 = 25
5n = 5 x 5 = 25
So 25 - 25 + 3 = 3
So the answer is 3
