Peter has a box containing 65 red and blue balls. Counting them, he realizes that there is a ratio of 3 red balls to 10 blue balls. How many blue balls does he have in total?
He started out with 47 balls after winning 2 blue balls and losing 3 red balls.
What is equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation.
The "=" sign and terms on both sides must always be present when writing an equation. Equal treatment should be given to each party.
Here,
Let the number of blue balls be x and the number of red balls be y,
after 5 days ,
x + 10 = y - 15
after 9 days ,
x + 18 = 2 * ( y - 27 )
subtracting both,
8 = y - 39
y = 47
The number of red balls in beginning is 47.
He had 47 balls in the beginning as he win 2 blue ball and lose 3 red balls.
Therefore, He started out with 47 balls after winning 2 blue balls and losing 3 red balls.

how to mitigate a DDos attack
WHAT IS DDOS MITIGATION?
DDoS mitigation refers to the process of successfully protecting a targeted server or network from a distributed denial-of-service (DDoS) attack. By utilizing specially designed network equipment or a cloud-based protection service, a targeted victim is able to mitigate the incoming threat.
There are 4 stages of mitigating a DDoS attack using a cloud-based provider:
Detection - in order to stop a distributed attack, a website needs to be able to distinguish an attack from a high volume of normal traffic. If a product release or other announcement has a website swamped with legitimate new visitors, the last thing the site wants to do is throttle them or otherwise stop them from viewing the content of the website. IP reputation, common attack patterns, and previous data assist in proper detection.
Response - in this step, the DDoS protection network responds to an incoming identified threat by intelligently dropping malicious bot traffic, and absorbing the rest of the traffic. Using WAF page rules for application layer (L7) attacks, or another filtration process to handle lower level (L3/L4) attacks such as memcached or NTP amplification, a network is able to mitigate the attempt at disruption.
Routing - By intelligently routing traffic, an effective DDoS mitigation solution will break the remaining traffic into manageable chunks preventing denial-of-service.
Adaptation - A good network analyzes traffic for patterns such as repeating offending IP blocks, particular attacks coming from certain countries, or particular protocols being used improperly. By adapting to attack patterns, a protection service can harden itself against future attacks.
Choosing a DDoS mitigation service
Traditional DDoS mitigation solutions involved purchasing equipment that would live on site and filter incoming traffic. This approach involves purchasing and maintaining expensive equipment, and also relied on having a network capable of absorbing an attack. If a DDoS attack is large enough, it can take out the network infrastructure upstream preventing any on-site solution from being effective. When purchasing a cloud-based DDoS mitigation service, certain characteristics should be evaluated.
