Answer:
4n - 13
Step-by-step explanation:
(5+10n)-(18+6n)
Distribute the negative sign.
-1(18)=(-18) & -1(6n)=(-6n)
5+10n + (-18) + (-6)n
Combine like terms.
10n + (-6n) = 4n
(-18) + 5 = (-13)
4n + (-13)
or
4n - 13
Answer:
Each page of the album contains 8 cards.
Step-by-step explanation:
Let us assume that each page of the album contains x number of cards.
Now, Mr. Harrid gave each of his two children an equal number of his baseball card collection.
He gave Tony an album with cards on 15 pages and a stack of 25 cards that still need to be put in the album and he gave his daughter Paula an album that has 10 cards and a stack of 65 cards to put in her album.
Therefore, Tony has (15x + 25) cards and Paula has (10x + 65) cards.
Hence, (15x + 25) = (10x + 65)
⇒ 5x = 40
⇒ x = 8
Therefore, each page of the album contains 8 cards. (Answer)
So, 7h/2=28.
Multiply by 2 to get 7h=56.
Divide by 7 to get h=8.
Therefore, the height is 8.
