The switching circuit is 24 Volts DC which connects a circuit of 250 Volts AC with a limit of 5A current.
Note: This is presumption based on how a relay works and its purpose.
5A, denotes ampere rating of dry contact for a 250VAC and/or 24VDC load.
The "pick up" of a relay is a setting at which the relay will begin to operate. Such as an overcurrent relay - if the pickup is set to 5A, when 5A is flowing through the relay, the relay will operate.
incase of numerical realys- if the relay is placed at a longer distance then we use 1A so that losses are less. incase of EM relays- if the relay is placed at shorter distance then we use 5A so that it improves the sensitivity of the relay. But i do not know why cant we use 4A instead of 5A?

6a + 4 = 5a - 2 means that 6a - 5a = -2 - 4 which gives a = -6
The answer depends upon what the "x" here means. x is commonly used in algebra to denote a variable. However "x" is also a symbol used to mean multiplication. If the first then 5xa means 5 multiplied by x multiplied by a. If the second then 5xa means 5 multiplied by a. This is usually written simply as 5a.
5a^(3) if the x means multiplication. 5a^(3)x^(3) if the x is a variable.
The GCF is 5a.
5a = -5a + 5Add 5a to each side:10a = 5Divide each side by 10:a = 5/10 = 1/2
(5a)^2 or a^2+10a+25
10
2a - 5a = -3a
