a positive number is 7 times another number. If 15 is added to both the numbers, then the one of the new number becomes 5/2 times the other new number. What are the numbers.
Answers
Answer:
f(x2 + y2, x2 - u2)=0. Solution: (a) ... uy/u = /. 1 - a2/y . Putting value of a from the first one into the second one gives the PDE.) (d) uxy - uyx = ... du/u2 x - y which gives dx x2. + dy y2. + du u2. = 0 ⇒ 1/x + 1/y + 1/u = c1 .
Step-by-step explanation:
Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3500 to 3000 BCE.
