2/3x -14/3 = -2 -foiled
2/3x = -6/3 +14/3 -common denominator
2/3x = 8/3
x = 8/3 * 3/2
x = 24/6
x= 4
Answer:
1.
Step-by-step explanation:
Note that 2^4 - 2^3 = 16 - 8 = 8 = 2^3
In a similar way 2^6 - 2^5 = 64 - 32 = 32 = 2^5.
So 2^99 - 2^98 = 2^98 , 2^98 - 2^97 = 2^97 , 2^97 - 2^96 = 2^96 and so on.
Therefore when we come to the last 2 terms we have 2^1 - 2^0 = 2 - 1
= 1 , so the answer is 1.

Answer:
20% =1/5
1/5 out of 25= 1/5*25/1=25/5=5
So 5oz -amount of ounces of alcohol in solution.
Solution is then 5oz alcohol + 20oz water =25oz
Add 50oz water
25(already existing) + 50 =75oz New solution
Still only 5oz of alcohol
5/75 =0.06666
Convert to percentage by multiplying result with 100.
Answer: 6.666%
