Take out a common factor between 3x and kx. That means use the distributive law to get what you normally would start with.
x(k + 3) = 4
Now divide by k + 3
x = 4/(k + 3)
That's as much as you can do with this question.
Answer:

Step-by-step explanation:
Let first day=a1
Tripled followers everyday
Second day=a2=a1×3
Third day=a3=a2*3
Fourth day=a4=a3*3
Fifth day=a5=a4*3
a=8 followers
a2=a1×3
=3*8
=24 followers
a3=a2*3
=24*3
=72 followers
a4=a3*3
=72*3
=216 followers
a5=a4*3
=216*3
=648 followers
On the fifth day, Alex will have a total of 648 followers on his new social media account.
Answer:
Smallest number = 3500
Step-by-step explanation:
Rounding of numbers involve replacing numbers with simpler numbers. In order to round a number to the nearest thousand, the last 3 digits of the number should be considered. If the last 3 digits are less than 500, the number is rounded down(the thousand figure is unaffected), but if the last 3 digits are greater or equal to 500, the number is rounded up.
In this case, Yuri is thinking of a 4-digit whole number and he rounds his number to the nearest thousand. Since his answer is 4000, the smallest number yuri could be thinking of would be 3500 and the highest number he could be thinking of is 4499.
Thus, the smallest number Yuri could be thinking of is 3500
