This equation simplified would be 2x^2.
Since we have terms that are not like (one has a variable and the other doesn't), we simply put them together when being multiplied.
x^2 * 2 = 2x^2
Answer:
x = (cy+b)/a
Step-by-step explanation:
ax-b=cy
Add b to each side
ax-b+b=cy+b
ax = cy +b
Divide each side by a
ax/a = (cy+b)/a
x = (cy+b)/a
In constructing an inequality, you need to know the following:
1. What don't we know? How many songs can be bought? So, let x be the numbers of songs.
2. What do we know? Each songs costs $2 plus a fee for using the artist's site of $5.
3. Is there more than 1 possible solution? Yes, because there is enough money left if she only bought 1 song.
The meaning of no more than $40 means it must not exceed $40, $40 or less, or only $40.
So, song + fee can't be more than $40 and song + fee could equal to $40.
Therefore, song + fee for using an artist's site less than or equal to $40.
Final Answer: 2x+5 <= 40
Hey there!!
Equation given :
A = h ( a + b ) / 2
Multiply by 2 on both sides
2A = h ( a + b )
Divide by h on both sides
2A / h = a + b
Subtract by b on both sides
2A / h - ( b ) = a
Hence, the option ( a ) is the correct answer
Hope my answer helps!
