Answer:
2 2/5
Step-by-step explanation:
Going off the idea that this is 4/(y+2) - 9/(y-2) = 9/(y^2-4), let's first rewrite y^2-4 in the form of a^2-b^2, where a=y and b=2.
y/(y+2)-9/(y-2)=9/(y^2-2^2)
Now, use difference of squares: a^2-b^2=(a+b)(a-b)
4/(y+2)-9/(y-2)=9/((y+2)(y-2))
Multiply both sides by the Least Common Denominator: (y+2)(y-2)
4(y-2)-9(y+2)=9
Then keep on simplifying until you get your answer
-5y-26=9
-5y=9+26
-5y=35
y=35/-5
y=-7
Yay! Our answer is y=-7!
Answer:
The answer is 53,333 rounded
Step-by-step explanation:
So you multiply 74,000 by 2/3 you get 49,333
Then you take that number and add 4,000 and you get 53,333 rounded.
986 Divided by 26 =37.92... but i do not know what partial quotients means
