25^(n-3)=5^(n+8)
Remember: 25=5²
Therefore:
5^[(n-3)²]=5^(n+8)
5^(2n-6)=5^(n+8)
Then:
2n-6=n+8
2n-n=8+6
n=14
Answer: n=14
First you need to combine like terms.
9x + 11y + 13
A coefficient is the number that comes before the variable (which is y).
The coefficient for y is 11.
Constants are the numbers that do not have variables attached to them.
The constant is 13.
Hope this helps!
Answer:
-5.4c
Step-by-step explanation:
We're combining two "like" terms here.
It may make the problem easier to visualize if we write one of these terms over the other, as follows:
-2.6c
- 2.8c
----------
Adding, we get:
-2.6c
- 2.8c
----------
- 5.4c (answer)
