The answer is no. Because solution (a,b) means x=a, y=b.and we have a-b=5. And (b,a) would mean x=b and y=a but then x-y=b-a=-(a-b)=-5≠5. So the pair (b,a) is not a solution.
Hello!
We know that 1 minute = 60 seconds.
5 minutes = 300 seconds because 60 × 5 = 300
360 seconds would be 6 muinutes. 420 seconds would be 7 minutes. That means 480 seconds = 8 minutes, so 8 minutes have passed.

Answer:
in any numerical computation; numerical values can only be rational numbers
Step-by-step explanation:
Any time a number is written down as a numerical value, it is a rational number. The numerical values we give to π or e or any root, logarithm, trig function, and polynomial solution are, of necessity, rational approximations to the true value. An "exact" value for an irrational number cannot be written down, so it must be approximated any time its numerical value is needed.
