Not if you know your mathmatics
1 is D, 2 I'm not sure, 3 is a and b, 4 is a.
Answer:
k = 2
Step-by-step explanation:

8k = 16
k = 2
If Myra has m stamps, then Rick has m-150.
Together, they have 500.
Therefore, m+m-150=500
2m-150=500
2m=650
m=325.
Therefore, Myra has 325 stamps, and Rick has 175 (325-150).
Hope this helps you:)
Given:

To find:
The value of
.
Solution:
We need to find the value of:

It can be written as


By using the property of logarithm, we get
![[\because \log \dfrac{a}{b}=\log a-\log b]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Clog%20%5Cdfrac%7Ba%7D%7Bb%7D%3D%5Clog%20a-%5Clog%20b%5D)

On substituting the given values, we get


Therefore, the values of
is -0.222.
