Answer:
The simplified expression is:

Step-by-step explanation:
We have those following logarithmic properties:



In this problem, we have that:

Applying these properties


Let the prices of a pack of potato chips and can of coke be x and y respectively
3x+2y=50-9
3x+2y=41........... (1)
4x+5y=50+21
4x+5y=71............(2)
Multiply (1) with 4 and (2) with3
12x+8y=164
12x+15y=213
On subtracting above eqs. we get
7y= 49
y=7
Putting value of y in (2)
4x+5(7)=71
4x+35=71
4x=36
x=9
x=$9
y=$7

Answer:
36
Step-by-step explanation:
Break it into parts to make it easier. The equation would become 16+12+8 which is 36
Multiply 5/2 on both sides to clear the fraction.
-8(5/2)=(5/2)(2/5)(k-2)
-20 = k -2
Add 2 to both sides
-18 = k
