The given addition exercise is:

The LCM of the denominator (5 and 3) = 15
Multiply 2/5 by 3/3

Multiply 1/3 by 5/5

The addition becomes

Therefore, we can fill in the vacant boxes as shown below:
Answer:
A. (-13,-3)
Step-by-step explanation:
Solve the system of two equations:

From the second equation:

Substitute it into the first equation:

So,

The solution is (-13,-4)
Answer:
-9
Step-by-step explanation:
Using the sum/difference property of logarithms, we can rewrite the expression given as:
log b^3 + log c^3 - log √(a^3) --> log √(a^3) can also be written as log a^1.5
Next, we can use the power property of logarithms, and rewrite it again as:
3log b + 3log c - 1.5log a
Now, we can substitute the values of log a, log b, and log c:
3(11) + 3(-9) - 1.5(10)
33 - 27 - 15
-9
Simplifying, we get -9 as the answer.
